摘要: The data acquisition system, designed for the Donner 600-Crystal Positron Tomograph, is described. Coincidence timing resolution of less than five nanoseconds full width at half maximum and rates in excess one million events per second are achieved by using high-speed emitter coupled logic circuits, first-in first-out memory to derandomize flow, parallel architecture increase throughput. These allow adequate transmission a reasonable amount time. Good minimizes accidental coincidences permits greater 100,000 image-forming dynamic emission tomography. Additional scatter rejection accomplished an orbiting source look-up table valid events. Calibration this complex electronic system performed automatically under computer control.
