A multi-channel digital silicon photomultiplier array for nuclear medical imaging systems based on PET-MRI
نویسندگان
چکیده
We present a 4 × 4 array of digital silicon photomultipliers (DSiPMs) capable of timestamping up to 48 photons per D-SiPM and we show the advantage of generating multiple timestamps in the context of positron emission tomography (PET). The D-SiPMs have a pitch of 800 μm and comprise 416 pixels each; the timing resolution achieved by the SiPMs is 179 ps FWHM, while each pixel has a fill factor of up to 57 % and a single-photon timing resolution of 114 ps.

Initial results of simultaneous PET/MRI experiments with an MRI-compatible silicon photomultiplier PET scanner.
UNLABELLED The most investigated semiconductor photosensor for MRI-compatible PET detectors is the avalanche photodiode (APD). However, the silicon photomultiplier (SiPM), also called the Geiger-mode APD, is gaining attention in the development of the next generation of PET/MRI systems because the SiPM has much better performance than the APD. We have developed an MRI-compatible PET system base...

Currently, for most photomultiplier tube (PMT)-based PET systems, constant fraction discriminators (CFD) and time to digital converters (TDC) have been employed to detect gamma ray signal arrival time, whereas anger logic circuits and peak detection analog-to-digital converters (ADCs) have been implemented to acquire position and energy information of detected events. As compared to PMT the Gei...

Recently, positron emission tomography (PET) is playing an increasingly important role in the diagnosis and staging of cancer. Combined PET and X-ray computed tomography (PET-CT) scanners are now the modality of choice in cancer treatment planning. More recently, the combination of PET and magnetic resonance imaging (MRI) is being explored in many sites. Combining PET and MRI has presented many...
متن کاملDevelopment of Si-PM Based Imaging Systems for Molecular Imaging
Silicon photomultiplier (Si-PM) is a promising photodetector for PET for the use in magnetic resonance imaging (MRI) systems because it is insensitive to static magnetic fields. Si-PM is also a promising for high resolution PET systems due to its small channels and high gain. We have developed several Si-PM based imaging systems for molecular imaging. First, we developed a high resolution Si-...
