Abstract: The disclosed embodiments relate to a system that performs ultra-fast tracer imaging on a subject using positron emission tomography. During operation, the system performs a high-temporal-resolution, total-body dynamic PET scan on the subject as an intravenously injected radioactive tracer propagates through the vascular system of the subject to produce PET projection data. Next, the system applies an image reconstruction technique to the PET projection data to produce subsecond temporal frames, which illustrate the dynamic propagation of the radioactive tracer through the vascular system of the subject. Finally, the system outputs the temporal frames through a display device.

Abstract: A detector for use in a dedicated PET scanner for cancer applications, particularly breast cancer applications, using a LSO scintillator, a lightguide coupling arrangement, and an efficient way to construct the scintillator array, which provides a flexible imaging system for breast cancer applications with high sensitivity and high spatial resolution in a compact, cost effective, design.

Abstract: A gamma ray detection and locating system comprising an array of scintillator crystals connected to a multichannel photomultiplier tube by discrete optical fibers, each fiber connecting a single crystal to a corresponding specific location on the face of the photomultiplier tube. Also described is an improved system for identifying the location of specific electrodes in the photomultiplier tube receiving electrons generated by photons flowing from the crystal along the fiber to the tube.
