摘要：
A specialized source of quasi-monochromatic X-ray radiation for medical application is proposed. It includes two electron storage rings (E approximate to 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 similar to1eV 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 multifold increasing of the noise-to-signal ratio and decreasing radiation doses for patients and personnel is shown.
