Recent Developments in Compton Tomographic Imaging of the Lung and Possible Application to Object Recognition

Compton Tomographic Imaging, using external sources and gamma camera, has been demonstrated to be an effective tool for producing 3-D images of the density distribution of the chest. The design aspects of the TomoCompton and the algorithm applied for correcting the acquired tomograms for both geometrical and physical attenuation are described. In vitro and in vivo studies are reported. Finally, a possible application of the TomoCompton in the area of object defects recognition is examined.
