While PET-CT imaging holds promise for simulation-free radiotherapy workflows, its inherent image resolution limits its use for accurate tumor and organ-at-risk (OAR) contouring. This study aims to enhance the spatial resolution of PET-CT by leveraging a reso...

To test whether commonly used pixel-wise CT reconstruction metrics reflect preservation of clinically relevant anatomy for radiotherapy imaging, and to develop an anatomy-centered, task-based evaluation and enhancement approach for sparse-view reconstruction.
