Abstract :
The evolution of gamma-ray imaging is traced and a new gamma-ray transverse section tomographic instrument is described which matches the favorable properties of wide-aperture focusing collimators to a form of the Radon equation which requires only angular averages of line integrals for reconstructions. Single slice scans of less than 5 minutes are accomplished with amounts of radioactivity that are standard for procedures using gamma cameras.
