Limited angle PET system

Positron emission tomography (PET) is a crucial diagnostic tool in modern medicine, providing three-dimensional imaging of functional processes within the body. This method detects two gamma rays originating from the point of annihilation of the positron emitted by a radio-labeled agent and utilizes them to follow physiological processes in humans. In Time-Of-Flight PET, gamma rays' arrival time is measured, in addition to their position, to improve the accuracy of imaging. State-of-the-art scanners have a coincidence timing resolution between 200 ps and 500 ps FWHM, which significantly enhances contrast in imaging large objects. However, next-generation PET scanners require substantial improvements in timing accuracy to enhance sensitivity. We propose a PET device with limited angular coverage consisting of four-panel detectors with a coincidence time resolution of about 100 ps FWHM. This project aims to develop and validate this device to be useful in next-generation PET scanners, enabling various applications from devices with limited angular coverage to total body PET devices. The technology has many competitive advantages, including dramatically reduced PET apparatus costs, and making diagnostics more accessible to healthcare systems.
