METHOD OF PHASE ROENTGENOGRAPHY OF OBJECTS AND GEAR FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 1998 - IPC

FIELD: production of X-ray image of internal structure of slightly absorbing objects, specifically, medico-biological ones. SUBSTANCE: method is based on refraction of nearly flat wave. There are used slightly diverging beams. Image is focused by means of Bragg reflection from perfect monocrystal-analyzer. In gears designed to provide for mutual orientation, adjustment and accuracy of maintenance of angular position of all element s of circuit for generation of high-quality image are achieved. Optimization of parameters provides for increased sensitivity and quickness, for contrast and adequacy of images. EFFECT: increased efficiency of method and gear, generation of high-quality images of internal structure of slightly absorbing objects. 50 cl, 9 dwg
