In PET/CT, the photosensors and readout electronics as well as the cooling infrastructure are placed radially behind the scintillation crystals (c.f. Fig.1). This enables short-axial FOV units, that can be extended to long aFOV systems by adding multiple copies of such ring-shaped gantries....
Cycling is a sport that consists of several competitive disciplines, such as track cycling, mountain-bike, para-cycling and bicycle motor cross, however the most common discipline is road cycling. Road cycling can be generally classed as an endurance sport where performance is conventionally determine...
Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…

The signal slope\(\frac{\textsf{dS}}{\textsf{dt}}\)increases with increasing number of detected photons (considering a short time period smaller the SPAD signal rise time). Therefore, the electronic noise plays an inferior role in PET measurements, which exploit scintillation emission in contra...
CT, lesions with a diameter less than the theoretical image resolution can still be detected if their contrast is sufficiently high; this is frequently seen in applications of [124I]-iodide and [68Ga]-somatostatin and -PSMA ligands due to the combination of high binding affinity and low back...
Adenosine triphosphate (ATP) is the energy currency within all living cells and is involved in many vital biochemical reactions, including cell viability, metabolic status, cell death, intracellular signaling, DNA and RNA synthesis, purinergic signaling, synaptic signaling, active transport, and muscle ...
When the FOV is set to 320 mm to cover the entire lung, the theoretical pixel size is 0.625 mm for a 512 × 512 matrix, 0.313 mm for 1024 × 1024, and 0.156 mm for 2048 × 2048. In HSR CT scans, a larger matrix size maintains spatial resolution, improves image ...
