106. Is sub-100 picosecond time resolution feasible in realistic TOF PET systems?

Dr Dennis Schaart (Delft University of Technology)

9/6/14, 3:30 PM

The use of time-of-flight (TOF) information in positron emission tomography (PET) significantly improves image quality. Commercially available TOF-PET systems currently have a coincidence resolving time (CRT) of ~500 ps FWHM. The TOF benefit is inversely proportional to the CRT. In recent years, several groups have achieved experimental CRTs of about ~100 ps FWHM at the bench-top level, using...

108. Electronics and data acquisition for PET systems based on silicon photosensors in general

Joao Varela (Univeristy of Lisbon)

9/6/14, 3:50 PM

We present the requirements, challenges and possible implementations of the frontend electronics and the data acquisition systems for high-performance PET systems based on silicon photosensors. Two use cases, namely the APD-based breast scanner ClearPEM and the SiPM-based detector of EndoTOFPET-US, are used as illustrations. The application to a large sensitivity whole-body scanner with long...

107. TOFPET ASICS

Manuel Rolo (INFN - Torino)

9/6/14, 4:10 PM

The TOFPET is a low power, low noise SiPM readout ASIC targeted, but not limited to, Time-of-Flight applications. It consists of a 64-channel analogue block, calibration circuitry, golden-references, bias generators and a global controller, featuring all-LVDS digital interface. It integrates signal conditioning and discrimination circuitry and high-performance TDCs for each of its 64...

109. PET signal optimization for different tasks: from lesion detection to pattern definition

Vesna Sossi (University of British Columbia)

9/6/14, 4:30 PM

Important goals in clinical medical imaging are early disease detection, disease staging and ability to establish treatment efficacy; they all require the ability to reliably detect small changes in the appropriate biomarker distribution. High imaging resolution and sensitivity and accurate data quantification are important elements, but so is the use of appropriate tracers and image...

110. Silicon Photo-Multipliers: status and perspectives

Dr Gianmaria Collazuol (PD)

9/6/14, 5:10 PM

Silicon photo-multipliers (SiPM) are novel type of photo-detectors whose success is growing in various scientific fields. They are compact devices composed of a few thousands of tiny avalanche photo-diode pixels grown on a common silicon substrate. The diodes are operated in Geiger mode so that any single carrier, generated either by photons or thermally in the depletion region, might trigger...

111. Analog SiPM

Hamamatsu

9/6/14, 5:30 PM

112. Digital Photon Counting (DPC, dSiPM) technology - Scalable light detection for high sensitivity medical systems

York Haemisch

9/6/14, 5:50 PM

Solid-state light detectors have significant advantages over photomultiplier tubes (PMT’s) such as ruggedness, compactness and insensitivity to magnetic fields, low operating voltage, power consumption and large scale fabrication possibilities using proven technologies and processes such as CMOS. Recently, the Silicon Photomultiplier (SiPM) gained momentum as a candidate to replace PMT’s in...

113. Reconstruction software

Charalampos Tsoumpas (University of Leeds, United Kingdom)

9/6/14, 6:10 PM
