X-RAY TOMOGRAPHY IN SCATTERING MEDIA

In this paper we treat the problem of tomography of a medium with a hi gh scattering level. A mathematical approach has been developed for an investigation of the radiation field. Based on these results a specia l source-detectors configuration is proposed. This offers a separation of the intensity of nonscattered and single-scattered radiation from the intensity of the total flux. The conventional Radon transform proc edure can be applied to the data processed that way to reconstruct the extinction coefficient distribution. Then the value of the scattering coefficient at any given point can be found separately by solving a s ystem of simple equations. Finally, we present some numerical results to demonstrate a numerical implementation of the method and the distor tion of the body image caused by scattering interference.
