Abstract :
The opportunities for the application of a compact pulsed power generator for medical diagnostics complex are considered. The converter placed behind the test object is irradiated by a short-duration packet of nanosecond X-radiation pulses. This operating mode of the apparatus is made feasible by using a high-voltage generator and an X-ray tube that permit attaining an X-radiation pulse duration of ~10-8 s, a value which is well below the duration of the return motion of the videocamera frame scanning beam (~2*10-3 s) at a pulse repetition rate of 10 kHz. Using highly intensive nanosecond X-radiation pulses has enabled us to obtain the highest intensity of luminescence of the luminophor as the intensity of luminescence is known to be proportional to the ionization rate of luminescence centers or to radiation power. We have obtained results on tests of an apparatus with a high-sensitivity CCD camera affording in the X-ray image a gray-color gradation level of 65536
