Advancements in TOF-PET using DOI Capable Modules and Low-Noise High-Frequency Readout / Terragni, G (CERN ; Vienna U.) ; Kratochwil, N (CERN) ; Lowis, C (CERN ; RWTH Aachen U.) ; Pagano, F (CERN ; INFN, Milan Bicocca) ; Cates, J W (LBNL, Berkeley) ; Pizzichemi, M (CERN ; INFN, Milan Bicocca) ; Marton, J (Vienna U.) ; Auffray Hillemanns, E (CERN)
Achieving good time resolution has become a prerequisite in positron emission tomography (PET) to improve the signal-to-noise ratio and thus the quality of the reconstructed image. A particularly attractive solution for the electronic readout is using low-noise high-frequency circuits (HF), which have demonstrated excellent timing performance in time-of-flight (TOF)-PET applications.

Comparison of timing and DOI performance of light-sharing TOF-PET modules with different readout electronics / Terragni, G (CERN ; TU Vienna) ; Nadig, V (RWTH Aachen U.) ; Di Gangi, S (Milan Bicocca U.) ; Marton, J (TU Vienna) ; Schulz, V (RWTH Aachen U.) ; Gundacker, S (RWTH Aachen U.) ; Pizzichemi, M (CERN ; Milan Bicocca U.) ; Hillemanns, E Auffray (CERN)
Time resolution plays a key role in positron emission tomography (PET) by enhancing the signal-to-noise ratio and ultimately improving the quality of the image. In previous studies, an array of 16 LYSO crystals (measuring 3.1x3.1x15 mm$^3$) coupled to Hamamatsu S13361-3050AE-04 SiPMs and readout by a custom-made NINO board achieved a coincidence time resolution (CTR) below 160 ps.

TlCl: Be, I: towards a superior Scintillation and Cherenkov emitter for medical imaging / Kratochwil, N (UC, Davis ; CERN) ; Kaneshige, N (Radiat. Monitor.

The material requirements for gamma-ray detectors for medical imaging applications are multi-fold and sensitivity is often overlooked. High effective atomic number (Zeff) Cherenkov radiators have raised the attention in the community due to their potential for harvesting prompt photons.A material with one of the highest Zeffand thus low gamma-ray attenuation length is thallium chloride (TlCl).

The emerging field of ultra-fast timing has enormous potential in high-energy physics, nuclear medicine, and imaging, and is driving advances in detector and readout electronics. To achieve improved time resolution, significant efforts have been devoted to this field, resulting in impressive coincidence time resolution (CTR) values for silicon photomultiplier (SiPM) and scintillator crystals using state-of-the-art high-frequency (HF) readout.

Time Resolution Studies of Thallium Based Cherenkov Semiconductors / Terragni, Giulia (CERN ; Milan Bicocca U.) ; Pizzichemi, Marco (CERN ; Milan Bicocca U.) ; Roncali, Emilie (UC, Davis (main)) ; Cherry, Simon R (UC, Davis (main)) ; Glodo, Jaroslaw (Radiation Monitoring Devices, Inc., Watertown) ; Shah, Kanai (Radiation Monitoring Devices, Inc., Watertown) ; Ariño-Estrada, Gerard (UC, Davis (main)) ; Auffray, Etiennette (CERN) ; Ghezzi, Alessio (Milan Bicocca U.) ; Kratochwil, Nicolaus (CERN ; Vienna U.)
In the context of improving the detector performance of time-of-flight positron emission tomography (TOF-PET), the combination of charge induction readout and prompt Cherenkov photon production in semiconductor materials can lead to an outstanding detector performance in energy, timing, and spatial resolution. Energy resolutions as good as 1.2% at 662 keV and 5% at 122 keV are reported for pixel thallium bromide (TlBr) detectors. [...]
