TL;DR: The results show a fast converging of activity-ranges measured by the prototype PET with high sensitivity and uniform resolution, which indicates the feasibility of PET for intra-fraction beam-range verification.

TL;DR: It is demonstrated that SSPM arrays and advanced readout/processing electronics can be used to develop a practical DOI-measureable PET scanner and the quality of PET images of both a hot-rod phantom and mouse acquired with DOI was much higher than that of images obtained without DOI.

TL;DR: A practical resistor-based multiplexing circuit that can be readily applied for reading out a large SiPM array with good detector performance is designed and implemented.

TL;DR: In this paper, the authors explored a capacitor-based multiplexing method for PET detector to read SiPM with a common cathode which has not been addressed previously, and the results showed that signal rise and fall times from different channels were similar, no output signal undershot, and no timing shift among different channels.

TL;DR: It is expected that standard shielding of detectors, electronics and signal transfer lines can be applied for simultaneous PET/MR imaging applications, with desired DOI measurement capability to enhance the PET performance and image quality.
