Abstract

A prototype high purity Germanium detector array designed for use in the pulse height analysis mode as a discrete photon energy detector for medical imaging was fabricated and tested. Results obtained as a function of the photon input rate, energy resolution, and techniques for correcting for pulse overlap at high count rates will be discussed. The ability to detect small. quantities of contrast agents, and the discrimination of photoelectric and Compton images is greatly enhanced by utilizing this detection technique, in theory, and the experimental results obtained from a 1x5 cooled array will be presented.
