PET-TOF study of Silicon Photomultipliers with DRS4 Readout
نویسندگان
چکیده
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 capacitance. We used a fast waveform digitizer to readout the SiPMs.

BGO as a hybrid scintillator / Cherenkov radiator for cost-effective time-of-flight PET.
Due to detector developments in the last decade, the time-of-flight (TOF) method is now commonly used to improve the quality of positron emission tomography (PET) images. Clinical TOF-PET systems based on L(Y)SO:Ce crystals and silicon photomultipliers (SiPMs) with coincidence resolving times (CRT) between 325 ps and 400 ps FWHM have recently been developed. Before the introduction of L(Y)SO:Ce...
متن کاملDevelopment of high-resolution detector module with depth of interaction identification for positron emission tomography
We have developed a Time-of-flight high resolution and commercially viable detector module for the application in small PET scanners. A new approach to depth of interaction (DOI) encoding with low complexity for a pixelated crystal array using a single side readout and 4-to-1 coupling between scintillators and photodetectors was investigated. In this method the DOI information is estimated usin...
متن کاملA novel, SiPM-array-based, monolithic scintillator detector for PET.
Silicon photomultipliers (SiPMs) are of great interest to positron emission tomography (PET), as they enable new detector geometries, for e.g., depth-of-interaction (DOI) determination, are MR compatible, and offer faster response and higher gain than other solid-state photosensors such as avalanche photodiodes. Here we present a novel detector design with DOI correction, in which a position-se...
متن کاملImproved image quality using monolithic scintillator detectors with dual-sided readout in a whole-body TOF-PET ring: a simulation study.
We have recently built and characterized the performance of a monolithic scintillator detector based on a 32 mm × 32 mm × 22 mm LYSO:Ce crystal read out by digital silicon photomultiplier (dSiPM) arrays coupled to the crystal front and back surfaces in a dual-sided readout (DSR) configuration. The detector spatial resolution appeared to be markedly better than that of a detector consisting ...
متن کاملPerformance of Silicon Photomultiplers with the CMS HCAL Front-End Electronics
We have measured the performance of silicon photomultipliers (SiPMs) together with the front-end electronics developed for the Compact Muon Solenoid hadron calorimeter. We find a clean separation of the single PE peak above pedestal noise fluctuations, providing a signal to noise of about 8. The SIPMs may be useful in the near term for readout of the outer (HO) scintillators to significantly en...
