INTRODUCTION
DigiMedXisacompleteeconomicradiographicequipment.ItusesDDR–DirectDigitalRadiological–image
acquisitionandcovers95%ofconventionalX‐rayexaminations.
DigiMedXhasbeenanalysedbyWHO–WorldHealthOrganisation–andcomplieswiththeirWHO/DIL/00.1
Rev1standardrequirements.
Incollaborationwith20medicalradiologicalcentresallaroundtheworld,WHOstudiestheoptimaldesign
for a radiological stand. DigiMedX follows this design and brings the additional benefits of a digital image
acquisition easy process. So any conventional exposure can be done on a patient in a standing, sitting or
lyingposition.Optionalaccessoriesareavailableforgeometricalmagnification.
DigiMedXgeneratorisbatteryoperated.Soitcanbeusedinareawherethepowersupplyisnotefficientor
not available all the time. A main 4A main supply at 230VAC is enough to power the complete system. It
couldalsobesuppliedbyasmallpowergroupof1.5kVA.
The tube stand with its swivel arm is very easy to use. The movements are well balanced and the arm is
locked in place by electromagnetic brakes. A additional safety detector avoids accidental collision of the
imagedetectorwiththefloorduringrotationandtranslationmovements.
