We are studying novel detection concepts to enhance coincidence time resolution (CTR) for time-of-flight (TOF) positron emission tomography (PET). In this short talk we will briefly discuss fundamental limitations on PET CTR using scintillation detectors and describe new configurations and electronic readout designs that attempt to address those constraints. We also concisely describe an...
"4D-PET is a new scanner dedicated to the brain examination. The scanner is based on an innovative detector design, that obtains full 3D impact position of the gamma ray inside the detector crystal, while providing also a precise (in the order of 250ps) determination of its impact time. The detector design is based on crystal slabs that allow also for good Depth of Interaction measurement,...
The utilization of polarization correlations of gamma-rays originating from para-positronium annihilation is emerging as an important additional handle to identify true coincidences in Positron Emission Tomography (PET) showing the potential to improve the signal to noise ratio in this imaging modality [1-3]. It was demonstrated experimentally that the polarization correlations of annihilation...
Registration of gamma quanta is a fundament for many experiments from the field of physics, as well as in nuclear medicine. One of the approaches for its enabling is provided by the means of plastic scintillator detectors. Developed by the J-PET Collaboration multi-purpose device - J-PET tomograph [1,2], consists of axially arranged plastic scintillator strips, read out at both ends by a pair...
