They have built 3 pairs of detectors and tested performance in terms of crystal identification, spatial, energy and timing resolution. The detectors consisted of 12/spl times/12 arrays of 1/spl times/1/spl times/10 mm LSO crystals (1.15 mm pitch) coupled to Hamamatsu H7546 64 channel PMTs via 5 cm long coherent glass fiber bundles. Optical fiber connection is necessary to allow high packing fraction in a ring geometry scanner. Fiber bundles with and without extramural absorber (EMA) were tested. The results demonstrated an intrinsic spatial resolution of 1.12 mm (direct coupled LSO array), 1.23 mm (bundle without EMA) and 1.27 mm (bundle with EMA) using a -500 micron diameter Na-22 source. Using a 330 micron line source filled with F-18, intrinsic resolution for the EMA bundle improved to 1.05 mm. The respective timing and energy resolution values were 1.96 ns, 21% (direct coupled), 2.20 ns, 23% (bundle without EMA) and 2.99 ns, 30% (bundle with EMA). Peak-to-valley ratio in the flood histograms was better with EMA (5:1) compared to the bundle without EMA (2.1:1). These detectors substantially improve on the performance characteristics of the detectors in the authors' current microPET scanner.","PeriodicalId":445100,"journal":{"name":"2000 IEEE Nuclear Science Symposium.

The authors present a conceptual design of a compact positron tomograph for prostate imaging, using a pair of external curved detector banks placed above and below the patient. The lower detector bank is fixed below the patient bed, and the top bank adjusts vertically for maximum sensitivity and patient access. Each bank is composed of 40 HR+PET block detectors, forming two arcs (44 cm minor, /spl sim/60 cm major axis) that are tilted to minimize attenuation and positioned as close as possible to the patient to improve sensitivity. The individual detectors are angled to point towards the prostate to minimize resolution degradation in that region. Inter-plane septa extend /spl sim/5 cm beyond the scintillator crystals to reduce random and scatter backgrounds. A patient is not fully encircled by detector rings in order to minimize cost, causing incomplete sampling due to the side gaps. Monte Carlo simulation (including randoms and scatter) demonstrates the feasibility to detect a spherical tumor of 2.5 cm diameter with a tumor to background of 2:1, requiring a number of counts that should be achievable with a 2 minute scan after a 10 mCi injection (e.g. carbon-11 choline).","PeriodicalId":445100,"journal":{"name":"2000 IEEE Nuclear Science Symposium.

It is based on the electronics for a human brain PET camera (the Siemens/CTI HRRT), modified to use a detector module that incorporates a photodiode (PD) array. An ASIC services the PD array, amplifying its signal and identifying the crystal of interaction. Another ASIC services the photomultiplier tube (PMT), measuring its output and providing a timing signal. FPGAs and lookup RAMs are used to apply crystal by crystal correction factors and measure the interaction depth (based on the PD/PMT ratio). Further arrays of FPGAs provide event multiplexing, derandomization, coincidence detection, and real-time rebinning. Embedded PC/104 microprocessors provide communication, real-time control, and configure the system. Extensive use of FPGAs make the overall design extremely flexible, allowing many different functions (or design modifications) to be realized without hardware changes. Incorporation of extensive onboard diagnostics, implemented in the FPGAs, is required by the very high level of integration and density achieved by this system.","PeriodicalId":445100,"journal":{"name":"2000 IEEE Nuclear Science Symposium.
