Performance measurements of a depth-encoding PET detector module based on position-sensitive avalanche photodiode read-out.
We are developing a high-resolution, high-efficiency positron emission tomography (PET) detector module with depth of interaction (DOI) capability based on a lutetium oxyorthosilicate (LSO) scintillator array coupled at both ends to position-sensitive avalanche photodiodes (PSAPDs). In this paper we present the DOI resolution, energy resolution and timing resolution results for complete detecto...
متن کاملDesign and performance evaluation of a compact, large-area PET detector module based on silicon photomultipliers
A PET module that comprises a pair of compact, high-resolution and large-area detectors based on silicon photomultipliers (SiPM) was developed and evaluated. The detector’s effective area was 24 mm!24 mm. LYSO crystals measuring 1.9 mm!1.9 mm!10 mm and charge division circuit were employed to obtain high spatial resolution with relatively concise Front-end electronics (FEE). Initial results sho...
متن کاملA compact PET detector module using SiPMs and MVT digitizers
Huazhong University of Science & Technology, Hubei, China Nowadays the simultaneous PET/MRI is being paid more and more attentions. Since MRI provides a high resolution, unsurpassed soft tissue contrast imaging and PET reveal the metabolism progress in molecular level, it is reasonable to believe the PET/ MRI will be a powerful tool to improve the understanding of pathogenesis and mechanism of ...
متن کاملSelf-Balancing Position-Sensitive Detector (SBPSD)
Optical position-sensitive detectors (PSDs) are a non-contact method of tracking the location of a light spot. Silicon-based versions of such sensors are fabricated with standard CMOS technology, are inexpensive and provide a real-time, analog signal output corresponding to the position of the light spot. An innovative type of optical position sensor was developed using two back-to-back connect...
متن کاملDevelopment of a fast position-sensitive laser beam detector.
We report the development of a fast position-sensitive laser beam detector. The detector uses a fiber-optic bundle that spatially splits the incident beam, followed by a fast balanced photodetector. The detector is applied to the study of Brownian motion of particles on fast time scales with 1 A spatial resolution. Future applications include the study of molecule motors, protein folding, as we...
