New imaging systems in nuclear medicine: Technical progress report
The Physics Research Laboratory of the Massachusetts General Hospital has been in the forefront of the field of nuclear medicine instrumentation for the past thirty-six years, particularly in the area of instrumentation dealing with the application of short-lived cyclotron-produced isotopes. We continue to improve the operation of PCR-I, a single ring demonstration system employing analog coding to achieve high resolution (4 to 5 mm), high sensitivity (45,000 c/s/ Ci/cc) and high sampling frequency without interpolative motion. This device is designed for brain imaging in humans and for animal studies. An intensive program of software development was carried out concurrently with hardware development and led to the PL/S computer system used for PCI and PCII. Subsequently, more powerful systems were developed using a Data General Eclipse computer and, more recently, an IBM PC/AT computer with array processor. Our laboratory is now engaged in a design study of a cylindrical positron tomograph (PCR-II). 136 refs., 6 figs., 1 tab.
