Advances in position-sensitive photodetectors for PET applications
This paper presents a brief review of the use of position-sensitive detectors in positron emission tomography (PET) together with an overview of the near-future perspectives. Special attention is given to the development of a new class of magnetic field-compatible solid state photodetectors, the so-called silicon photomultipliers (SiPM). & 2009 Elsevier B.V.

متن کاملExploring spatial resolution in high-sensitivity nanogap quantum dot photodetectors.
We propose a new approach to experimentally determine the spatial resolution of nanogap quantum dot (QD) photodetectors consist of solution-processed QDs. Cross talk between a pair of closely positioned QD photodetectors was measured. Devices with 200 nm spacing exhibit low crosstalk of 8.4%. A single QD photodetector also shows high sensitivity, with a lowest detectable optical intensity of 95...
متن کاملPreparation and Quality Control of 68Ga-Citrate for PET Applications
Objective(s): In nuclear medicine studies, gallium-68 (68Ga) citrate has been recently known as a suitable infection agent in positron emission tomography (PET). In this study, by applying an in-house produced 68Ge/68Ga generator, a simple technique for the synthesis and quality control of 68Ga-citrate was introduced; followed by preliminary animal studies. Methods: 68GaCl3 eluted from the ge...
متن کاملVery High Resolution Small Animal PET
Positron Emission Tomography (PET) is a leading technique in medical diagnostic imaging. PET scanners are used to detect cancerous cells through the use of a positron emitting tracer that is ingested by the patient. The positron annihilates with an electron in the body producing a pair of 511keV gamma rays emitted in opposite directions. The gamma rays are sufficiently energetic to leave the pa...
متن کاملIntegrated High-Resolution Multi-Channel Time-to-Digital Converters (TDCs) for PET Imaging
PET with time-of-flight (TOF) capability has been shown to provide a better reconstructed image compared to conventional positron tomography. The increase in SNR mainly depends on the size of the patient being imaged Conti (2009), the intrinsic resolution of the detector and the resolution of the TOF. In TOF-PET approach, for each detected event, the measurement of the time of flight difference...
