Title: Characterization of a PET Camera Optimized for ProstateImaging

Abstract

We present the characterization of a positron emission tomograph for prostate imaging that centers a patient between a pair of external curved detector banks (ellipse: 45 cm minor, 70 cm major axis). The distance between detector banks adjusts to allow patient access and to position the detectors as closely as possible for maximum sensitivity with patients of various sizes. Each bank is composed of two axial rows of 20 HR+ block detectors for a total of 80 detectors in the camera. The individual detectors are angled in the transaxial plane to point towards the prostate to reduce resolution degradation in that region. The detectors are read out by modified HRRT data acquisition electronics. Compared to a standard whole-body PET camera, our dedicated-prostate camera has the same sensitivity and resolution, less background (less randoms and lower scatter fraction) and a lower cost. We have completed construction of the camera. Characterization data and reconstructed images of several phantoms are shown. Sensitivity of a point source in the center is 946 cps/mu Ci. Spatial resolution is 4 mm FWHM in the central region.

  • The depth-of-interaction effect in block detectors degrades the image resolution in commercial PET cameras and impedes the natural evolution of smaller, less expensive cameras. A method for correcting the measured position of each detected gamma ray by measuring its depth-of-interaction was tested and found to recover 38% of the lost resolution in a table-top 50 cm diameter camera. To obtain the desired depth sensitivity, standard commercial detectors were modified by a simple and practical process, which is suitable for mass production of the detectors. The impact of the detector modifications on central image resolution and on the ability of themore » camera to correct for object scatter were also measured.« less
  • An extensive computer simulation has been completed to design a new type of scintillation camera for nuclear medicine. The aim of the design is to adapt the Anger camera to perform well at higher gamma energies, especially 511 keV. Such a design should provide an economic alternative to the small-crystal ring tomograph for PET, as well as improved efficiency for single photon ECT in the energy range 140-511 keV. A prototype has been constructed to test the new ideas arising from the design study. The prototype incorporates a 5 cm thick sodium iodide scintillator coupled to a rectangular array ofmore » 64 small photodetectors. Intrinsic position resolution measurements, as well as a variety of other measurements, have been performed at gamma-ray energies of 122 keV and 514 keV.« less
  • One of the major design goals of the TOFPET I positron camera was to produce a high resolution whole body positron camera capable of dynamically imaging an organ such as the heart. TOFPET I is now nearing completion and preliminary images have been obtained to assess its dynamic and three dimensional imaging capabilities. Multiple gated images of the uptake of Rubidium in the dog heart and three dimensional surface displays of the distribution of the Rubidium-82 in the myocardium have been generated to demonstrate the three dimensional imaging properties. Fast dynamic images of the first pass of a bolus ofmore » radio-tracer through the heart have been collected with 4 second integration time and 50% gating (2 second equivalent integration time) with 18 mCi of Rb-82.« less
  • This is a study of the effects of geometric asymmetries in circular photomultipliers (PMT) on the design of PET position-sensitive block detectors. The dynodes of linear-focus circular PMT`s are asymmetric relative to the axis of the photocathode, despite the rotational symmetry of the photocathode. Hence, there are regional photocathode differences in the anode signal, which affect the decoding characteristics of position sensitive block detectors. This orientation effect, as well as the effect of introducing light diffusers, are studied in a block detector design (BGO) using the PMT-quadrant-sharing configuration. The PMT studied is the Philips XP-1911 (19mm diameter). Seven symmetrical andmore » representative orientations of the four decoding PMT were investigated, as well as one asymmetric orientation. The measurements performed include block-composite pulse-height spectra and crystal decoding maps. Two orientation effects were observed: (A) distortion variation in decoding maps, and (B) decoding resolution variation. The introduction of circular plastic pieces, used as light diffusers, prove to be useful by improving the decoding of crystals on the periphery of the detector block and minimizing distortion in the decoding map. These measurements have shown optimal PMT orientations for the PMT-quadrant-sharing design, as well as for conventional block designs.« less
  • This is an electronic design for a PET camera with 8 arrays of position sensitive detectors. Each array has 16 BGO blocks (each block is composed of 49 crystals). The design goals are component and space reduction. Each PMT has its fast amplifier and triggered integrator. Nine flash ADC serve an array of 27 PMT and 784 crystals. The fast signals from one or more PMT clusters are summed. The fast summed signals are thresholded and sent to a programmable logic to determines the probable scintillation zone (4 blocks) and to turn on the associated 9 PMT integrators. After integration,more » the logic also drives a set of ultra-fast analog switches to connect the flash ADC set to the PMT integration channels in the scintillation zone. The 9 ADC output (integrated pulses with good photon statistics) are latched and compared. The comparator result determines which block in the zone is firing and the appropriate 4 ADC are selected and bused into a position decoder. The decoder outputs the image-slice address and the crystal address. The circuit is pipelined and driven by a 250 MHz master clock. The maximum event-processing rate for the circuit and a random radiation source is 2 x 10{sup 6}/sec (with 10:1 randomness allowance).« less
