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 …

Task-based assessment of binned and list-mode SPECT systems

MA Rahman, AK Jha - Medical Imaging 2021: Image …, 2021 - spiedigitallibrary.org
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 …
