PET-TOF study of Silicon Photomultipliers with DRS4 Readout
Our goal is to develop a system with 100 picosecond time resolution for time of flight positron emission tomography [PET-TOF] using silicon photomultipliers (SiPMs). We have obtained a coincidence time resolution of 188 ps FWHM with two LYSO crystals (3x3x15 mm) coupled to SiPMs and irradiated with Na source. The best time resolution was obtained with the signal trimmed by a clipping capacitanc...
متن کاملFirst results with SiPM tiles for TOF PET based on FBK RGB-HD technology
Fondazione Bruno Kessler, Trento, Italy We present the first results of timing and energy resolution of two newly developed tiles based on FBK RGB-HD SiPMs. The first tile has dimensions of 32×32 mm and is composed of 8×8 SiPMs, with a regular pitch of 4 mm and a cell size of 25×25 μm. Although manufactured with a standard bond wire technology, the tile achieves a fill factor at the tile level ...
متن کاملScintillator Tile Hadron Calorimeter with Novel SiPM Readout
The CALICE collaboration is presently constructing a test hadron calorimeter (HCAL) with 7620 scintillator tiles read out by novel photo-detectors Silicon Photomultipliers (SiPMs). This prototype is the first device which uses SiPMs on a large scale. We present the design of the HCAL and report on measured properties of more than 10 thousand SiPMs. We discuss the SiPM efficiency, gain, cross-ta...
متن کاملProof of concept of an imaging system demonstrator for PET applications with SiPM
A PET imaging system demonstrator based on LYSO crystal arrays coupled to SiPM matrices is under construction at the University and INFN of Pisa. Two SiPM matrices, composed of 8 8 SiPM pixels, and 1,5 mm pitch, have been coupled one to one to a LYSO crystals array and read out by a custom electronics system. front-end ASICs were used to read 8 channels of each matrix. Data from each frontend w...
متن کاملAnalog electro-optical readout of SiPMs for compact, low power ToF PET/MRI
Department of Radiology, Stanford University, Stanford, CA 94305, USA The aim of this work is to demonstrate time of flight (ToF) performance from analog electro-optical transmission of SiPM-based PET detector signals. In electro-optical readout schemes, scintillation signals are converted to near-infrared light by a laser diode and transmitted out of the MRI bore with fiber-optics [1], greatly...
