INPA Seminar Speaker: Seungeun Lee (LBL)- Title: Scintillation photon counting detector concept for advancing time-of-flight PET
January 30 @ 12:00 pm - 1:00 pm
Date: January 30, 2026
Time: 12:00 pm – 1:00 pm
Location: Sessler Conference Room – 50A-5132 [Hybrid and In-Person]
Speaker: Seungeun Lee (LBL)
Title: Scintillation photon counting detector concept for advancing time-of-flight PET
Abstract: Positron emission tomography (PET) is a powerful imaging modality for providing in vivo molecular function in nuclear medicine. The precise timing capability of positron annihilation photon interaction within the scintillation detectors has remarkably revolutionized the diagnostic performance of PET, motivating the radiation instrumentation researchers to pursue sub-100-ps time resolution at the system level. The biomedical imaging team at LBL ANP is currently developing a novel time-of-flight PET detector concept that extracts unique timestamps of the early scintillation photons for event timing and positioning. This approach integrates a large-volume scintillation crystal, silicon photomultipliers, and low-noise high-frequency readout electronics. Our recent progress in design optimization and prototype characterization will be presented.
