The Multi-Pixel Photon Counter (MPPC), also called silicon photomultiplier (SiPM), together with ASIC and TDC forms the key detection technology in the TOF-PET module. Excellent coincidence resolving time (CRT), high energy resolution, and low power consumption are required in TOF-PET detectors. We developed signal processing boards optimized for SUPER TOF-PET with low power consumption, requiring only 1.3W, which combines the ASIC, TDC, HVPS, and FPGA. A CRT of 200ps has been achieved with improvements to the detection efficiency and dark noise. A TOF-PET module that achieves 150ps CRT is our next target for further improvement by using sub-pixel readout.

Dino Butron is a Senior Applications Engineer at Hamamatsu Corporation in Bridgewater, NJ where his focus is on high sensitivity photodetectors for use in various markets. He is currently involved in leading discussions for detector selection and developing simulation tools. Dino is an expert in the operating principles and application of various detectors such as photodiodes, avalanche photodiodes (APD), SPPC (SPAD), MPPC (SiPM), and photomultiplier tubes (PMT). He has worked on many photodetector experiments resulting in a deep understanding of detector performance. In addition, he has vast knowledge programming signal-to-noise ratio and output simulations. He received his Bachelor’s degree in Electrical Engineering from Manhattan College, Riverdale, NY, in 2012.
Dr. Martin Janecek is a Technology Development scientist at Hamamatsu Corporation. His work is focused on PET, SiPMs, SPADs, and other optical sensor technologies and their applications. Martin Janecek received his M.Sc. from Chalmers University in Goteborg, Sweden, and his Ph.D. from UCLA, working under the mentorship of Ed. Hoffman. His postdoc at Washington University in St. Louis was focused on developing the virtual-pinhole PET system, working under the leadership of Yuan-Chuan Tai. Before joining Hamamatsu, Martin worked in William Moses’ and Steve Derenzo’s groups at Lawrence Berkeley National Laboratory, developing technology for next generation PET scanners, and at Rapiscan Systems, developing x-ray transmission and x-ray diffraction baggage scanners.
