Abstract
Gamma-ray detectors for the detection of one or more gamma-rays are provided. Also provided are methods of using the detectors for the detection of one or more gamma-rays. The detectors can be used in high-spatial resolution PET systems, including time-of-flight (TOF)-PET systems. Some of the gamma-ray detectors utilize fluors and an optical imaging system to determine the time and location of a first scattering event of a gamma-ray in a low atomic number scintillating medium. Some of the gamma-ray detectors determine the time and location of a first scattering event of a gamma-ray in a low-density scintillating medium by imaging scintillation photons from the scattering event as a time-series of photon “rings” using a planar pixelated photodetector as a scintillation photon counter.
