Impact on timing and light extraction of a photonic crystal as measured on a half patterned LYSO crystal: implications for time of flight PET imaging

Abstract: The improvement of the energy and of the timing resolution is always a challenge in scintillation-based detectors. A large fraction of the photons produced by scintillation remains trapped inside the crystal. Photonic crystals have been suggested as a solution to improve light extraction. Here we will present results obtained with a nanostructured TiO 2 coating on a 50 × 50 mm 2 LYSO crystal. The objective of the present paper is to characterize the performance of this coating in both light extraction and timi… Show more

“…The next steps concerning the PhC will consist in extending the experimental characterization to crystal needles as well as measuring the possible impact of the PhC on the spatial reconstruction on one side, and the temporal on the other in terms of timing performance. We expect an improvement of CRT as also suggested in [18,21,43,44]. Another interesting, though challenging perspective is represented by the simulation of the light interaction with the entire scintillator-photodetector interface and the scintillating crystal itself, to optimize the output gain.…”

“…Time-to-digital converters (TDCs) is a powerful device for measuring the arrival time of input signals from precise instruments or equipment. High-performance TDCs have been widely applied in many frontier scientific researches, such as medical diagnosis and imaging [1,2], time-correlated single photon counting (TCSPC) [3,4], space science [5], quantum communication [6][7][8], high energy physics detectors [9], light detection and ranging (LiDAR) [10], and time-of-flight (TOF) measurements [11,12].…”
