The effect of the scattered radiation produced on irradiating a body (K) with X-rays is eliminated by image reconstruction. This is achieved not by using a scattered radiation baffle in front of the detector field (DF), but by applying a solution to the physical problem. The number of scattered X-ray quanta is determined from the transport equation for the X-ray radiation. The detector measurement...
