A Bayesian approach to tissue-fraction estimation for oncological PET segmentation
Z Liu, JC Mhlanga, R Laforest… - Physics in Medicine …, 2021 - iopscience.iop.org
Tumor segmentation in oncological PET is challenging, a major reason being the partial-
volume effects (PVEs) that arise due to low system resolution and finite voxel size. The latter …

No-gold-standard evaluation of quantitative imaging methods in the presence of correlated noise
Objective evaluation of quantitative imaging (QI) methods with patient data is highly
desirable, but is hindered by the lack or unreliability of an available gold standard. To …

Task-based assessment of binned and list-mode SPECT systems
In SPECT, list-mode (LM) format allows storing data at higher precision compared to binned
data. There is significant interest in investigating whether this higher precision translates to …
