	Nowadays angiography has become one of the most commonly used medical procedures. However the X-ray tubes are mostly used in angiography imaging systems. The problem that encounters in using X-ray tubes is low monochromaticity due to bremsstrahlung while angiography imaging requires quasimonochromatic energy spectrum for better image quality and lower dose rate obtained by the patient. The use of the monocrystaline target at the medical electron LINAC can be one of the possible ways to obtain the monochromatic X-ray radiation. This type of X-ray generator will provide monochromatic radiation with photon energy dependent on the electron beam energy. The X-ray generation mechanism, possibilities of monocrystal usage as an X-ray source for angiography and requirements for beam parameters are discussed.

The use of the monocrystaline target at the medical electron LINAC can be one of the possible ways to obtain the monochromatic X-ray radiation. This type of X-ray generator will provide monochromatic radiation with photon energy dependent on the electron beam energy. The X-ray generation mechanism, possibilities of monocrystal usage as an X-ray source for angiography and requirements for beam parameters are discussed.
