We have evaluated the coincidence imaging performance of a monolithic detector block design for a human brain PET scanner by implementing a demonstrator based on two detector blocks. Each detector is composed of a monolithic LYSO:Ce scintillator coupled to a pair of Hamamatsu S8550-02 APD arrays with custom ASIC readout electronics. Results show that this design is suitable for our application and...
Novel conceptual design of Pixel-PET scanner, based on pixelated solid-state detector, is presented. Pixel-PET simply solves most of the intrinsic limitations that are inherited in the current PET scanners, and in particular those that are based on scintillating crystals, such as low detection efficiency, low energy resolution, low spatial resolution, parallax effect, image noise from scattered photons,...
The development of a prototype dual-modality optical and PET (OPET) small animal imaging tomograph is underway in the Crump Institute for Molecular Imaging at the University of California Los Angeles. OPET consists of a single ring of six detector modules with a diameter of 3.5 cm. Each detector has an 8times8 array of optically isolated BGO scintillators which are coupled to multichannel photomultiplier...
