E Radiation and Mechanical/Electrical Warning (from NEMA Standards Publication/No. XR8-1979) Radiation Warning for Diagnostic X-Ray Systems X-rays are dangerous to both operator and others in the vicinity unless established safe exposure procedures are strictly observed. The useful and scattered beams can produce serious, genetic or potentially fatal bodily injuries to any persons in the surrounding area if used by an unskilled operator. Adequate precautions must always be taken to avoid exposure to the useful beam, as well as to leakage radiation from within the source housing or to scattered radiation resulting from the passage of radiation through matter. Those authorized to operate, test, participate in or supervise the operation of the equipment must be thoroughly familiar and comply completely with the currently established safe exposure factors and procedures described in publications such as Sub-Chapter J of Title 21 of the Code of Federal Regulations, “Diagnostic X-Ray Systems and their Major Components”, and the National Council on Radiation Protection (NCRP) No. 33, Medical S-Ray and Gamma-Ray Protection for Energies up to 10 MeV-Equipment Design and Use, as revised or replaced in the future. Failure to observe these warnings may cause serious, genetic or potentially fatal bodily injuries to the operator or those in the area. Mechanical/ElectricalWarning for Diagnostic X-Ray Systems All of the moveable assemblies and parts of X-ray equipment should be operated with care. Only properly trained and qualified personnel should be permitted access to any internal parts. Live electrical terminals are deadly; be sure line disconnect switches are opened and other appropriate precautions are taken before opening access doors, removing enclosure panels or attaching accessories. Do not remove the flexible high tension cables from the X-ray tube housing or high tension generator or the access covers from the generator until the main and auxiliary power supplies have been disconnected. When disconnecting high voltage cables, they must be grounded immediately in order to dissipate any electrical charge that may remain on the cables or the tube. Failure to comply with the foregoing may result in serious or potentially fatal bodily injuries to the operator or those in the area. 1 THIS INSTALLATION AND OPERATION MANUAL MUST BE DELIVERED TO THE PURCHASER UPON COMPLETION OF THE INSTALLATION PRIOR TO RELEASE OF THE EQUIPMENT. 2 INSTALLATION OPERATORS MANUAL S/N 1000 AND UP 5.0/above Software REVISION 1 MANUAL # AC-4000 Rev-1 Notice This manual is copyrighted and all rights are reserved.

HF Radiographic System. This is one of the finest x-ray radiographic system designed for today’s market. HCMI, Inc. incorporates state of the art technology along with TRUE 100 kHz high frequency resonant power source, anatomically programmable technique selection and Quartz accurate electronics. Your new instrument is designed to provide you with years of service with proper maintenance and care. MANUAL OVERVIEW The HF Series Operation Manual is intended for use by technologists and field engineers. Four sections are enclosed. The first four provide the general information and system operation and diagnostic procedures necessary to operate the HCMI, Inc. HF 300 system. All other information regarding installation, troubleshooting and schematics can be obtained through our website at www.newhcmi.com or on the CD Rom provided with your system. ♦ Section A PREFACE - includes a system description, safety notices and recommendations, shipping information, compliance and x-ray protection notices and warranty information. ♦ Section B GENERAL INFORMATION - includes component specifications, system options, an overview of operating modes and a description of system controls and indicators. ♦ Section C SYSTEM OPERATION - provides completed operating procedures, including power on/off procedures, operation modes and exposure selection criteria. ♦ Section D SYSTEM DIAGNOSTICS - contains a description of error messages and a list of common system faults with suggested responses. ♦ Section E INSTALLATION – provides installation and interconnection procedures. ♦ Section F CALIBRATION – provides calibration procedures, including kVp, mA, and system electronics. Page 2 Section A PREFACE SYSTEM DESCRIPTION The HCMI, Inc. HF Generator is a anatomically programmable high-frequency x-ray generator. Operating at 100 kHz resonance, the system offers remarkable performance as a diagnostic tool with dramatic reductions in exposure times and patient radiation dose. The HF series accommodates up to 72 views for 2500 anatomically programmed techniques. After a thickness measurement is entered prior to exposure, the system automatically sets programmed x-ray techniques and exposure factors, including AEC mode (if available), tube selection, bucky selection, kVp, mA, and time. Programmed techniques can be modified at any time through the control panel, either in the actual stored program or during the current exam. During exposure, the AEC (optional) works in conjunction with Auto-Tech to provide uniform, repeatable, high quality images with the smallest variation of optical density between patients. The HF series is also available as a stored energy system that allows you to plug it into a standard power receptacle (110 VAC). Standard Configurations and Optional Features Standard Configurations The HF Series X-ray generators are state-of-the-art programmable systems. Since the requirements of radiological practices vary widely, HCMI, Inc.’s basic system design provides for easy future upgrades. The HF Series is available in four (4) base configurations, as follows: Single Phase Models: ♦ ♦ HF-300 HF-600 Stored Energy Models: ♦ ♦ HF-3SE HF-3SEE 110 VAC 50/60 Hz 220 VAC 50/60 Hz Note: Stored Energy models can be connected to a standard 110 VAC or 220 VAC power source. Page 3 Section A PREFACE Optional Features A variety of options provide the flexibility to meet individual requirements: ♦ Automatic Exposure Control (AEC) System: uses an ion chamber to assure proper exposure times. The anatomical program selects the kV, bucky, mA and focal spot prior to exposure; the AEC then terminates the exposure at the exact mAs required for a perfect image. This provides uniform film density from patient-to-patient and film-tofilm. ♦ Pedestal Mount (PDL-1000): free-standing unit offers maximum in operator access and convenience.

The following operating procedures are outlined and described in detail: ♦ Power on/off procedures ♦ Seasoning procedures ♦ Operating modes and selection: Auto-Tech, AEC and Manual ♦ Printing techniques Power On/Off Procedures The following are step-by-step procedures to power-on/off your system according to its status. There are three possible shut down states: 1. Complete Shut Down- The power switch and main circuit breaker were set to off. The power line might have been disconnected 2. Remote Shut Down- The system was shut down with the remote ON/OFF power switch on the Operator Control Panel (OCP). 3. Automatic Shut Down- Power to the system was automatically disconnected (via internal timing circuit) after sixty minutes of inactivity. To Power-on Your System: From A Complete Shut Down 1. If necessary, connect the power line into the appropriate power receptacle. 2. Set the main circuit breaker on the system to the ON position. 3. Set the remote power switch (located on the OCP) to the ON position. From A Remote Shut Down 1. Set the remote power switch to the ON position From An Automatic Shut Down 1. Set the remote power switch to OFF. 2. Wait five seconds, then set the remote power switch to ON. Page 2 Section C SYSTEM OPERATION Power-On Self Test ♦ When the HF Series generator system is first powered-on, “HCMI” appears on the display while the system automatically runs a series of self checks to ensure proper operation. If an error is detected, the actual error (i.e., “DOOR?”) will appear on the LCD. Upon successful completion of the self checks, the display will return to the last exposure setting that was used. To Power-Off Your System For Short Periods of Time 1. 2. Set the remote power switch on the OCP to the OFF position. Ensure indicators are dark. System is now shut down. For Long Periods of Time 1. 2. 3. Set remote power switch on the OCP to the OFF position. Locate the main circuit breaker on the generator and set to the OFF position. If desired, unplug the power line from the power receptacle or set the main power disconnect switch to the OFF position. System is now shut down. Automatic Power-Off Feature To help save power and protect system electronics when left unattended, the HF Series generator system is equipped with an automatic power-off feature that shuts down the unit. After approximately sixty minutes of inactivity, the system will automatically power-off through software control, leaving all switches in the ON position. An audible tone will be emitted for approximately 30 seconds before the system shuts down and “PRESS ANY KEY” will be displayed on the operator control panel. To Abort the Automatic Power-Off Feature: Press any key on the operator control panel. To Re-start after Automatic Shut Down: Refer to Power-On Procedures. Page 3 Section C SYSTEM OPERATION Full Charge Shutdown (Stored Energy Only) Occasionally, when the system has not been used for an extended period of time, or after a period of heavy use, a full charge shut-down is recommended. A full charge will help to restore the batteries to a sufficiently-charged condition. 1. Press arrow keys (See Figure 6-11, page 7 Sec F). 2. Leave the system in this state until the next day. 3. The next day, press MANUAL on the Utility Menu. System is ready for use. Daily Procedures Warm-Up Procedures All tube manufacturers recommend seasoning procedures upon installation and daily warm-up. Systems used infrequently should have tubes seasoned on a daily basis. It is important that these procedures be performed to maintain both the tube manufactures and HCMI, Inc.’s extended warranties. A typical daily seasoning procedure is provided below. If the system has not been used for several days, or upon installation, refer to the tube manufacturer’s instructions. Procedure: Table 3-1 Exposure Settings for Seasoning Procedures EXPOSURE NUMBER KVP 1 50 TIME (Seconds) 0.1 2 60 0.1 3 70 1.0 4 80 0.1 5 90 0.1 6 100 0.1 7 110 0.1 Page 4 Section C SYSTEM OPERATION Operating Modes The HF Series can operate in four modes: ♦ Manual ♦ Automatic Exposure Control (AEC) ♦ Auto-Tech ♦ Auto-Tech with AEC MANUAL MODE - requires manual calculation/selection of all x-ray techniques and exposure factors. AEC MODE - (optional) uses an ion chamber to ensure proper exposure times. Film density is selectable via key pad control through selection of AEC fields in use and pre-programmed film/screen combinations. AUTO-TECH MODE - enhances radiographic imaging by automatically setting technique factors. After a thickness measurement is entered, prior to exposure, the system automatically sets programmed x-ray techniques and exposure factors including AEC mode (if available), tube selection, bucky selection, kVp, mA, and time. Programmed Auto-Tech settings can be modified at any time through the OCP, either in the actual stored program or for the current exam. During exposure the AEC (optional) works in conjunction with Auto-Tech to provide uniform, repeatable, high quality images with the smallest variation of optical density between patients. AUTO-TECH WITH AEC MODE - after the technologist selects the anatomical view, the system selects and sets all the optimum technique factors prior to exposure, including the wall or table ION chamber. Setting Up To Take Exposures All aspects of x-ray techniques are entered at the OCP. Prior to taking an exposure, MODE, BUCKY and TUBE must be selected. In addition, the displayed exposure factors (mA, Time, kVp and mAs) should be verified. When operating in Auto-Tech mode, all x-ray techniques and exposure factors are automatically entered for you. Pre-Exposure Selections This procedure outlines step-by-step instructions to set up x-ray techniques and exposure factors prior to exposure. Since these procedures are mode and option dependant, refer to the appropriate operating mode to begin. A flow chart on page 6 (Figure 3-1) provides a graphic representation of the pre-exposure selection process. Selections are made by pressing the appropriate key on the OCP or the UP/DOWN arrows on the LCD portion of the LCD. Page 5 Section C SYSTEM OPERATION Pre-Exposure Selections continued Figure 3-1 Mode Selection Flow Chart Select an Operating Mode There are four possible modes of operation, depending on the options selected with your system. The two basic modes are Auto-Tech and Manual. Automatic Exposure Control (AEC) can be used as a stand alone mode (by itself) or in conjunction with Auto-Tech. 1. 2. 3. Select a mode of operation by pressing the appropriate key: AUTO-TECH, AEC, or MANUAL. Once selected, ensure that the corresponding indicator is illuminated. Continue with the required procedures as follows: AUTO-TECH Selected AEC Selected MANUAL Selected Go to Select Region of Interest Go to Select Density Go to verify/Select Tube and Bucky Page 6 Section C SYSTEM OPERATION Select Region of Interest When Auto-Tech is selected, x-ray techniques and exposure factors are automatically set according to your specific program. The Auto-Tech Menu (example shown in figure 3-2, below) will be displayed on the LCD. 1. Select the appropriate region of interest by pressing UP or Down sector key associated with the desired region. Figure 3-2 Auto Tech Menu Select an Anatomical View After the region of interest is selected, a selection of available anatomical views will be displayed. 1. Select the appropriate anatomical view by pressing the UP or DOWN sector key associated with the desired view (see figure 3-3). Anatomical names and/or designations can be modified, added or deleted from the program as described in Section G, Programming. Figure 3-3 Anatomical View Selection Menu Page 7 Section C SYSTEM OPERATION Verify/Select Measurement Selected SID is indicated by arrow as shown in Figure 3-4. 1. 2. If necessary, use the UP/DOWN sector keys on the LCD to increase or decrease the displayed cm. Initially, the CM value is set to 0. If AEC mode is available continue with Enter/Verify CM. Figure 3-4 AEC Mode Verify/Select AEC Density/Field When AEC is enabled, the AEC mode indicator is illuminated. A segment of the LCD displays the currently selected AEC field and film density setting (example shown in Figure 3-6). Available density settings (DNS value) are from +5 to -5. The 0 (zero) setting is depicted as N (normal), which is the initial setting. Density 1. To increase or decrease density, press the UP or DOWN sector keys in the DNS field, respectively. Each density step increases or decreases mAs by approximately 15%, which, in turn, increases or decreases density, respectively. AEC Field A configuration of three boxes depicted on the LCD displays currently selected fields. A shaded or hollow box indicates whether a field is used or unused, respectively. NOTE: Ensure that the appropriate BUCKY mode is enabled prior to AEC FIELD selection. 1. To select an AEC field, press one of the AEC Field keys until the desired configuration is displayed on the LCD. There are seven possibilities. Page 8 Section C SYSTEM OPERATION HCMI AEC Field Continued Figure 3-5 Auto Tech Menu (AEC On, AEC Field Select) Figure 3-6 AEC Mode Enabled, Field Selection Settings Verify/Select Bucky 1. In each operating mode, verify that the appropriate Bucky technique is selected (indicator illuminated). 2. If necessary, press the appropriate key: Wall Bucky, Table Bucky, or Non Bucky. 3. Continue with Verify/Select Exposure Factors. Verify/Select Exposure Factors In auto-Tech mode, exposure factors (mA, kVp and mAs) are programmed. However, you can modify any displayed factor or enter your own for manual or AEC modes. Once you have verified that all x-ray techniques and exposure factors are correct, you can prepare to take an xray exposure. Displayed exposure factor values (see example displays below) can be increased or decreased by pressing the UP or DOWN arrow keys associated with the factor. When techniques are modified from the original settings, UP/DOWN arrows are displayed next to the modified technique to indicate that its corresponding factor was increased or decreased. For example, as shown in Figure 3-8, mA was increased, kVp was decreased and mAs were decreased. Note: Values displayed are not necessarily correct techniques; they are used only as an example. Page 9 Section C SYSTEM OPERATION Verify/Select Exposure Factors continued Figure 3-7 Initial Auto-Tech Menu, Manual CM Entry Figure 3-8 Auto-Tech Menu with Modified Techniques Preparing To Take an X-Ray Exposure After exposure factors have been verified as above, ensure that all other x-ray exposure precautions are met. If you have not already done so, position the patient accordingly and ensure that the patient is comfortable. Refer to Image Quality (page 3-13) for additional suggestions. Taking Exposures For Instantaneous Exposures: 1. Press and hold PREP until the PREP lamp is lit steady. 2. Press and hold EXPOSE until the exposure is complete (system will emit an audible tone).

Coat the entire surface of the cable terminal insulator with insulating compound (supplied with cables) using clean, dry plastic spoon or wooden stick,. Do not use fingers. Fully cover the entire surface with a heavy coat (approximately 1/16 to 1/8 “). Build a pyramid at the tip of the plug with the height of the compound even with the contact ends. Page 8 Section E INSTALLATION High Voltage (High Tension) Cables continued 5. With terminal key in alignment with receptacle key-way, insert the cable terminal plug into its socket until all excess compound has oozed out. Make sure the contact pins are engaged in the holes in the socket insulator and wipe off any excess compound. 6. Tighten the cable nut while holding the cable firmly in place. Re-tighten after calibration as some loosening may take place after the housing has been heated and cooled. With cable nut properly tightened, secure with 10-32 X 1/4" locking screw. Figure 5-2 b High Tension Cable Installation 7. Place cover plates around the high voltage cables on the outside of the cabinet in order to close off large openings as shown in Figure 5-2c, page10, Sec E. Page 9 Section E INSTALLATION High Voltage (High Tension) Cables continued Figure 5-2c Cabinet Top Cable Assembly Page 10 Section E INSTALLATION Operator Control Panel Step 1 Remove the Operator Control Panel from its shipping box and mount in the location of your choice. The OCP includes a 20 foot interconnect cable, consisting of two ribbon cables and one power cable. If additional length is required, you may order this cable per foot, CP-C, for this cable configuration. Step 2 If the OCP is used with the optional pedestal (PDL) (shown Pre-Installation, pg D) or optional wall mount (HF-WM shown on page 12 Sec E), assemble and mount the OCP. Step 3 Connect OCP interconnect cables to power cabinet through cable entrance hole separate from all power cables (rotor, collimator, locks, etc.). Do not wire tie low voltage ribbon cables to high voltage or rotor cables. Attach one cable to A-272-J3 (microprocessor board) marked 272-J3 connect ground shield to ground. (Chassis). Attach one cable to A-198-J2 (LCD driver board) marked 198-J2 connect ground shield to ground. (Chassis). Step 4 Connect gray power cable (remote ON/OFF control) to TB1, connections 1 and 2 on the POWER SHUT OFF board (A-202). Page 11 Section E INSTALLATION Operator Control Panel continued Operator Control Panel Procedure for Assembly Bucky/Collimator Interconnections In general, bucky, table and tube housing assemblies are interconnected to the HF Series generator via the Interconnect Panel (A-Din Rail). Table 5-1 provides cable color codes and terminal connection data. Install the bucky according to the instructions provided with the bucky. Figure 5-4 is interconnection diagrams for bucky and collimator wiring. If a reciprocating bucky is installed in the table (Bucky 1), the jumper connection on interface board A Din Rail at COM 1 and CONT, must be removed. If a reciprocating bucky is installed in the wall (Bucky 2), the jumper connection on interface board A Din Rail at COM 2 and CONT must be removed. Please note that all system interconnections must be secured with the strain relief clamp. Page 12 Section E INSTALLATION Powering the System Power Connections 1. HF-300/600 Generators require a line disconnect box (or according to local code) before the x-ray generator. This switch should be within reach of the operator. A separate earth ground, #6 AWG insulated wire, (green with yellow stripe) must be installed. The ground wire must be the ONLY wire connected to the ground terminal. See Fig 5-2d for power connections L1 & L2 and ground. HF-3SE can be plugged into a standard switched 120 VAC grounded outlet. The outlet receptacle should be within reach of the Operators Control Panel (OCP). The HF-3SE unit is factory wired and tested at 120 VAC. Voltage ranges from 105-130 VAC, 50/60 HZ. Must be connected only. (See NOTE A, System Schematics). HF-3SEE units are 200 to 250 VAC, 50/60 HZ. (See NOTE A, System Schematics). Figure 5-2d Supply Conductor Connections Page 13 Section E INSTALLATION Verify Input Power Procedures 1. 2. 3. Using a calibrated DVM, measure the input line voltage. HF-3SE version can operate between 105 and 130 VAC; HF-3SEE version scan operate between 200 and 250 VAC. (Refer to Section B, Electrical Requirements, Figure 2-0). Adjust transformer to match the input line voltage as closely as possible. On non-SE models, the correct line location will yield 235 to 245 VAC measured between the 0 terminal and the 240V terminal. For non-SE models, it is necessary to insure that the line resistance meets requirements as stated in Section B, General Information, Figure 2-0 page 6. To measure line resistance, follow the next five steps. 1. Connect an Ohm/Stat to the incoming line and an AC voltmeter to terminals marked meter. 2. Measure the input voltage and record the Eo number (no load voltage). 3. Press the switch and record the Eb number (load voltage). 4. Calculate the Line Resistance using the following formula: RL =Rd (Eo-Eb) Example 2.75 (220-218) = 5.5 = 0.025 Eb 218 218 5. RL = Line resistance Eo = No Load Voltage Eb = Load Voltage Rd = Load Resistance (See Ohm/Stat for Rd value) Refer to Table 2-0 for the maximum acceptable line resistance; if line resistance exceeds the specification, contact factory. Calibrating the System After installation, the system must undergo a series of electrical checks. These are required to validate system compliance. Refer to Section F, Calibration, and proceed to calibrate the HF generator. Verifying Programmed Techniques After the calibration procedures have been completed, check the factory programmed techniques for individual preference. Reference Section G, Programming/Utilities for procedures to edit existing techniques or write new ones if and as needed.

Verify kV Calibration settings. Take several exposures out of calibration mode (60-7090 kV etc). Page 9 Section F CALIBRATION mA Calibration ! Warning: The following calibration procedures involve taking X-ray exposures. All personnel should be behind the protective barriers. X-rays can be dangerous unless proper precautions and procedures are followed. Caution: Excessive anode heat will effect mA Calibration accuracy. 1. To measure mA, use either a dynalyzer or Philips PM 2618 mAs meter or equivalent. a. If you are using a dynalyzer, it should be connected in series between the tube and anode H.V. tank. The cathode tank should be directly connected to the X-ray tube. The dynalyzer should be set for kVp trigger at 90%. In this set-up, kVp will read ½ of actual, but mA will be most accurate. b. If an mAs meter is used, disconnect the mA lead (purple/white) from the mA terminal on the anode H.V. tank. Connect the mAs meter in series between the mA terminal and the mA lead (purple/white) on the anode H.V. tank. This measurement may not be as accurate as when using the dynalyzer for times of 50 msec and below. c. When calibration is complete, disconnect the mAs meter and reconnect the mA lead (purple/white) to the anode H.V. tank mA terminal. 2. Access mA calibration mode as follows: (See figure 6-11) a. Press CAL MA directly from the kVp/mA Calibration Select Menu. b. Or, if power to the system has been off, set main power switch to ON.

Take an exposure and verify that the mA meter display indicates an mA value (see Specification Overview, Section B or page 11, Section F.) to the value displayed under CALIB (25S as shown above in Figure 6-14). Page 11 Section F CALIBRATION mA Calibration continued 4. If measured mA is within specification (as indicated in Section 2, General Information), continue with Step 5. If not, adjust the mA code up or down (by pressing the corresponding buttons on the LCD) to increase or decrease the mA code reading. Note: If the specified mA cannot be obtained using the available mA code range (0-255 mA), the resistance on Filament Resistor Board A186 must be increased (when 0 is reached) or decreased (when 255 is reached) as required. This may occur, for example, when the high tension cable length or the tube is changed. After changing resistance, repeat Step 4. 5. Repeat Steps 3 and 4 until the mAs meter reading and displayed mA value are within specification. When the measured and displayed values are within specification, press NEXT to calibrate at the next kVp steps. 6. Repeat the calibration procedure (steps 3 thru 5) for each mA station and using each kVp step. Each mA station requires calibration at each of the six (6) pre-set kVp/time steps. Note: When NEXT is pressed at the end of each mA station setting, the LCD momentarily displays a “Saving mA Code” message. During this time, the microprocessor is entering the calibration data. Caution: DO NOT OVERHEAT X-RAY TUBE: ALL SIX BREAK POINTS MUST BE ENTERED TO CALIBRATE mA. 7. After completion of all mA stations, set main power switch to OFF and reconnect the system. Maximum Deviation kVp, Time, mA, mAs 1. Set the dynalyzer for mA (90% trigger level on kVp). 2. Refer to the data sheet in Section 8, Planned Maintenance and Troubleshooting, and take exposures at the required settings. 3. Run a print-out and record on the data sheet. 4. Make sure that the following are within tolerance: a. mA- + 10% or 5mA, whichever is greater. b. kVp - + 5% c. Timing - + 1% + 3 milliseconds. Time is measured at the 90% level of the peak kV. d. mAs - + 12% for time greater than or equal to 100 milliseconds and current greater than or equal to 50 mA; otherwise, accuracy is a product of time and mA accuracies.

Mas should read approximately 3.6. Check 150L @ 120 kVp, mAs should read approximately 2.0. 12. To increase optical density of film at kVp setting 73 or below, turn R56 clockwise. To increase optical density of film at kVp setting of 74 and above, turn R55 clockwise. AEC Calibration, Expose Film and Measure Optical Density The following procedure requires film processing and measuring optical density with a densitometer. 1. Test film processor for optimum film development. ♦ Check developer temperature specifications. ♦ Check developer quality and specific gravity. ♦ Check film processor replenish rates. 2. Test film for base fog (should be less than .19 OD). 3. Test and verify film and cassette screens for correct match and speed (400 blue, 400 green, etc.). 4. Test darkroom safe-light. Process film exposed only to safe-light and measure optical density. Place a plastic container with 8-10 ”(inches) of water in the x-ray beam, load a film cassette and place in cassette tray. Measure optical density at 65 kVp and 105 kVp. * The two (2) films should not vary in optical density by more that .1. *The optical density of the first film is equal to the exposure mAs. Record the exposure mAs after the exposure, displayed in the mAs screen window. Measure optical density and calculate “target mAs” = (desired density divided by measured density) x elapsed mAs. Example: The elapsed mAs is 20 mAs and the density is 1.0 OD. Desired is 1.20 “target mAs” = (1.20 ÷ 1.0) x 20 = 24. The new mAs to achieve 1.20 OD will be 24 mAs.

Select measurement parameters with the CM STRT and CM INCR sector as described below. The CM STRT sector defines that start value (lowest possible selection) for the selected anatomical view. Possible selections are 1 through 16. The CM INCR sector defines the value by which the CM measurement will be incremented each time the CM select key is pressed. There are ten available selections. For example, if CM STRT is 1 and CM INCR is 3 for a selected view, some CM selection possibilities would be 1, 4, 7, 10, etc. In general, you should establish a CM range for the selected view. The CM range is the total thickness range of the desired anatomical region. If the CM range is 10 or less, use 1 as a CM increment. If the range is between 11 and 20, use 2 as a CM increment. If the CM range is between 21 and 30, use 3 as a CM increment. If the range is over 30, use 4 as a CM increment. a. To increase or decrease CM STRT value, press the appropriate up/down sector key until the desired value is displayed. Page 5 Section G PROGRAMMING UTILITIES Auto-Tech Programming Procedures (Continued) b. To increase or decrease CM INCR value, press the appropriate up/down sector key until the desired value is displayed. c. When BUCKY, CM STRT and CM INCR sectors display the desired values, press NEXT to advance to the Exposure Factor Selection Edit Menu (example shown below). Figure 7-6 Exposure Factor Selection Edit Menu 10. 11. You are now ready to select exposure factors for the selected view for each CM selection. For each CM setting, select a base kVp and mAs value. These set values can be manually modified for each individual exam, at random without returning to program edit mode. a. To increase or decrease displayed kVp setting, press the up/sown associated sector keys. b. To increase or decrease the displayed mAs setting, press the associated up/down sector keys. When the desired exposure factors for the displayed CM setting are displayed, press NEXT. Repeat step ll for each CM setting displayed. Note: If the optional AEC system is selected for this anatomical view, the AEC stop signal will terminate the x-ray. The programmed mAs setting will not be in effect (refer to Configure Operating Parameters in Section 6, Calibration for setting the AEC back-up time). The AEC may be turned off in this view by pressing the AEC key on the OCP. c. After the tenth CM setting has been set and NEXT is pressed, the edited x-ray techniques will be stored in memory. “PLEASE WAIT” will be displayed momentarily on the fifth sector. After the technique has been stored, the program edit menu will automatically advance to the next anatomical view. You can continue to edit or exit program edit mode. To edit additional x-ray techniques, repeat this entire process as necessary for each. To exit program edit mode and return to normal operating mode, press MANUAL key.
