Abstract. MPPS is a family of multi-pixel, self-quenching type Geiger Avalanche Photodiodes. We have been continuously improving the MPPC performances and getting better test results. We introduce some of resent progresses on the MPPC. ・ Dark current Decreasing ・ Wider Operating voltage ・ Metal Quenching resister to replace Poly-Si resister ・ Improve Time resolution ・ ...

25. STMicroelectronics Photodetectors Technology – From SPAD to Analog SiPMs

Dr G. Fallica

8/30/12, 10:40 AM

Abstract. Single Photon Avalanche Diodes (SPAD) and Silicon Photo Multipliers (SiPM) are high sensibility sensors with a great potential in heterogeneous insertion of optical technologies. They find main application in Healthcare, in particular inside Medical Image Systems for Nuclear Medicine like Single Photon Emission Computer Tomography (SPECT) and Positron Emission Tomography (PET). Among...

32. Strategies to Obtain Time of Flight Resolution in the 100 Picosecond Range.

Dr D. Schaart

8/30/12, 11:35 AM

Abstract. The use of time-of-flight (TOF) information in positron emission tomography (PET) significantly improves the image quality, in particular the signal-to-noise ratio. Commercially available TOF-PET systems have a CRT in the order of ~500 ps FWHM, which has been shown to significantly improve whole-body PET images. The TOF benefit is inversely proportional to the coincidence resolving...

26. Digital SiPM: Approaching the Cramer-Rao Limit in TOF-PET, Reliably and Robustly

Prof. E Charbon

8/30/12, 12:00 PM

Abstract. In this talk we look at digital SiPMs as an alternative to analog SiPMs, analyzing pros and cons of the two architectures, systematically from a theoretical and a practical perspective. The key advantage of digital SiPMs is not higher timing accuracy or better noise but rather higher tolerance to environmental variations and higher long-term robustness. Moreover, thanks to the...
