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...
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...
RapidArc Dynamic (RAD) in Eclipse, version 18.1 integrates dynamic collimator rotation with static angle modulated ports (STAMPs) into arc to improve plan quality and treatment time. Flattening filter–free (FFF) beams further reduce beam-on time through highe...
Radiation pneumonitis (RP) remains a major toxicity in thoracic radiotherapy. While lung radiomics has shown promise for RP prediction, the optimal region for feature extraction remains unclear. This study investigated whether restricting the extraction regio...
Jaw geometry in elongated fields substantially impacts output factors (OPFs); therefore, reliance on square-field data alone cannot account for the physical effects. This study evaluated the response characteristics of various small-volume detectors in high-a...
Predicting radiation pneumonitis (RP) using machine learning is promising, particularly when functional lung heterogeneity is incorporated via dose-function histogram (DFH) and CT ventilation imaging (CTVI). However, traditional dose–function metrics often fa...
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...
Accurate detector alignment is essential in MR-linac reference dosimetry to account for Lorentz force–induced dose perturbations. Current protocols, such as AAPM TG-351, recommend aligning the detector’s longitudinal axis parallel to the magnetic field (B0) t...
Grade ≥2 radiation pneumonitis (RP) occurs in approximately 30% of patients undergoing radiotherapy for lung cancer. Therefore, a predictive model to estimate RP risk before radiotherapy is required. Radiomics and dosiomics have shown potential for RP predict...
