Spine stereotactic body radiotherapy (SBRT) requires high precision due to the anatomical proximity of target to the spinal cord and steep dose gradients. Rotational setup errors (SE) can affect the dose delivery to targets and organs at risk (OAR). This stud...

Deep Learning-Based Auto-Segmentation of Spinal Cord and Thecal Sac In Stereotactic Body Radiotherapy for Spinal Metastases
Stereotactic body radiotherapy (SBRT) for spinal metastases requires accurate delineation of the spinal cord and thecal sac to maximize treatment efficacy while minimizing toxicity. Deep learning-based segmentation models improve contouring efficiency and red...

Radiomics- and Dosiomics-Based Machine Learning Models for Predicting 1- and 2-Year Local Failure after SBRT for Non-Spinal Bone Metastases
Stereotactic body radiotherapy (SBRT) for non-spinal bone metastases generally achieves high local control; however, approximately 10% of patients experience local failure (LF). Conventional clinical and dose metrics often fail to capture patterns associated...
