In vivo detection, localization, and measurement of radionuclides in man: a detection system for the localization and measurement of small amounts of photon emitters. Progress report, September 1, 1979-December 1, 1980
The objectives of this research involve the design, development, and testing of a new type of photon detection system which can provide, simultaneously, magnitude and positional data regarding a radioactive source, without utilizing a high-Z collimator. This system employs the principle of active collimation, i.e., the geometric configuration of crystal elements results in certain members being shielded from oblique-angle rays, thereby providing spatial resolution characteristics. Inasmuch as events occurring in the promontory shielding crystals can be used to determine activity levels of the emitter, a greater counting efficiency is attainable than that with other currently available systems. Owing to optical and scintillation characteristics, and amplifier parameters, along with masking of the common PM tube, each of the five scintillation crystals in the detector configuration produces a separate, delineable spectral peak.
