Scattering Tomography

Abstract
An X-ray tomographic system is described for observing biological materials and for medical diagnosis. In this method scattered X-rays produce a tomographic image, expressing a certain relationship between the scattering point and the recording point, on a multi-color cathode-ray-tube (CRT). We call this method scattering tomography (ST). The apparatus consists of scanning mechanisms for the sample and an electron beam CRT, two circular slits, a solid state detector, pulse-height analysers and other necessary electronic circuits. The ST images are in many cases, completely different from those obtained using conventional radiography or computed tomography. The scattering tomogpraphy system provides a useful tool for medical diagnosis and for studying biological materials in which neither conventional radiography nor computed tomography would be helpful.
