X-Ray Tomography Vs Compton Scattering in the Diagnosis of Pulmonary Diseases

A comparative study in various pulmonary conditions has been carried out using the methodologies of X-Ray Tomography and Compton Scatter Imaging. This last technique is based on the detection of the photons scattered at 90° by the chest tissues, using a LFOV gamma camera. The radiation source is made up of a laminar beam of photons generated by a twin of 2Ci Ir-192 sources. (1, 2).
