[Determination of the efficiency of registration of X-ray diagnostic systems by visually detected minimal radiation contrast].
Described in the paper is a relatively simple method for the determination of the efficiency of registration of X-ray diagnostic systems by the whole tract of transformation of radiation contrast from the spot of contrast-sensitivity test to the visual registration of image. It is just enough to have the contrast sensitivity test and to measure the dose at test location. On the basis of the visually registered minimal contrast the efficiency of registration of a diagnostic system is evaluated by the radiation-contrast parameter. The suggested method can be used at handover tests and in testing the X-ray systems during their exploitation.
