Exploring the performance of a DOI-capable TOF-PET module using different SiPMs, customized and commercial readout electronics.

Time resolution is crucial in positron emission tomography (PET) to enhance the signal-to-noise ratio and image quality. Moreover, high sensitivity requires long scintillators, which can cause distortions in the reconstructed images due to parallax effects. This study evaluates the performance of a time-of-flight (TOF)-PET module that makes use of a single-side readout of a 4x4 3.

Holistic evaluation of a machine learning-based timing calibration for PET detectors under varying data sparsity.

Modern PET scanners offer precise TOF information, improving the SNR of the reconstructed images. Timing calibrations are performed to reduce the worsening effects of the system components and provide valuable TOF information. Traditional calibration procedures often provide static or linear corrections, with the drawback that higher-order skews or event-to-event corrections are not addressed.

Timing limits of ultrafast cross-luminescence emission in CsZnCl-based crystals for TOF-CT and TOF-PET.

Background: Good timing resolution in medical imaging applications such as TOF-CT or TOF-PET can boost image quality or patient comfort significantly by reducing the influence of background noise. However, the timing resolution of state-of-the-art detectors in CT and PET are limited by their light emission process. Core-valence cross-luminescence is an alternative, but well-known compounds (e.

Therapeutic Dilemma: Acute Myocardial Infarction in a Patient with Traumatic Hepatic and Mesenteric Injuries: A Case Report.

ST-elevation myocardial infarction (STEMI) in a trauma patient with solid abdominal organ or vascular injuries can present complex diagnostic and therapeutic challenges. Evidence for managing such demanding cases is scarce, and isolated case reports remain the source of information in treating these patients. We present a patient with traumatic mesenteric and hepatic injuries who developed acute STEMI in the immediate postoperative period.
