Studies on three-dimensional scintigraphy with gamma - gamma -coincidences

Abstract

By means of phantom studies, it is shown that three-dimensional scintigraphy is possible with gamma - gamma -cascade isotopes, such as 75Se. Large plastic scintillators and slit collimators are proposed for additional coincidence detectors which observe one plane only. The necessary conditions for the technical performance of the apparatus are derived. Some suitable isotopes are discussed.
