Fig. 2From: Simulation study of a coincidence detection system for non-invasive determination of arterial blood time-activity curve measurementsSchematic detailing layout of the wristPET1 (a) system. wristPET1 consists of 14 detectors in a closed ring design, whereas a second system (wristPET2 (b)) was projected to employ an open-ring design with a subset of detectors (numbers 4-11) only. All other properties of the detectors between wristPET1 and wristPET2 are identicalBack to article page
