Standard clinical reconstructions usually require several minutes to complete, and this time
is mostly independent of the duration of the data being reconstructed. Applications such as …

A significant challenge during high-resolution PET brain imaging on PET/MR scanners is
patient head motion. This challenge is particularly significant for clinical patient populations …

Background In preclinical positron emission tomography (PET) studies an anaesthetic is used
to ensure that the animal does not move during the scan. However, anaesthesia may have …

Head motion during brain PET imaging can significantly degrade the quality of the reconstructed
image, leading to reduced diagnostic value and inaccurate quantitation. A fully data-…

Motion compensation (MC) in PET brain imaging of awake small animals is attracting increased
attention in preclinical studies since it avoids the confounding effects of anaesthesia and …

Purpose Data‐driven rigid motion estimation for PET brain imaging is usually performed
using data frames sampled at low temporal resolution to reduce the overall computation time …

PET iterative reconstruction typically employs subsetting to reduce computation time. List
mode PET data provides flexibility for subsetting approaches, but optimization of list mode …

Rigid image registration techniques can be used in PET imaging to align frames acquired
during a brain scan where motion may or may not have been present during the scan. The …

High resolution PET imaging is being driven by recent advances in both scanner hardware
and image reconstruction. As a result, images are being reconstructed with smaller pixel …

Head movement during PET acquisition degrades image quality and may render studies
non-diagnostic. Rebinning of the list mode data to reconstruct optimised images from a …
