A specialized source of quasi-?monochromatic X-?ray radiation for medical application is proposed. It includes two electron storage rings (E = 50 MeV) placed in the vertical plane and two laser resonators located in the horizontal and vertical planes. Hard X rays are generated in a process of back Compton scattering of laser photons ~1eV by electrons in the linear paths of storage rings. The scheme of the X-?ray beam sweeping over the predetermined region of interest for two-dimensional imaging is described. The possibility of multi-fold increasing of the noise-?to-?signal ratio and decreasing radiation doses for patients and personnel is shown.
