Compared to whole-body systems, DOI information gains additional importance, improving sensitivity and reducing parallax error [1]. We present a detector concept based on semi-monolithic slabs fulfilling these needs. Materials and methods The detector consisted of 8 monolithic LYSO slabs of dimensions...
(2014) proposed a design prospect for parallax errors at the edge of the Field of View (FOV) caused by DOI and poor image resolution consistency to investigate the performance of PET imaging detectors [14]. Cao et al. (2022) studied a PET detector with a time-of-flight (TOF) readout,...

it needs to be large enough to fit the animals into the scanner. A smaller diameter will also cause a larger parallax error (DOI effect). Hence, most of the PET research focuses on developing high-resolution PET detectors to improve the system-level resolution [52,70,107,134,156]. The ...

Additionally, radial resolution was relatively uniform over 5–15 mm radial offset from the centre of the FoV, indicating that the DOI method implemented on this system is effective at mini- mising resolution degradation due to parallax error. Beyond the NEMA guidelines, a micro-resolution ...

However, the spatial resolution and the associated partial volume effect (PVE) can vary significantly along the extended axial FOV of TB PET systems, especially if the parallax error is not accounted for by depth-of-interaction correction [9]. The PVE is inherent to PET imaging and can signifi...
FIG. 4A illustrates the well-known parallax error. Conventional commercial PET scanners do not measure the axial location of an interaction within the crystal (the depth of interaction, or DOI), but rather assign a constant value 80 to the DOI for all detected interactions, based on the attenu...
