Prostate High Dose-Rate (HDR) Brachytherapy with Dominant Intraprostatic Lesion (DIL) boost is well tolerated for high-risk patients. Ultrasound-guided prostate HDR is a time-sensitive procedure with treatment planning subject to variability, especially for s...

Understanding of medical physics is essential for safe and effective radiation oncology practice. This study evaluates current instructional practices for physics education in radiation oncology physician residency programs following the release of the AAPM/A...

Patient-specific quality assurance (PSQA) for lateral targets on a 1.5T MR-Linac (MRL) is limited by restricted couch motion and lack of dedicated positioning aids for off-axis measurements. While lateral ArcCheck-MR configurations can improve detector covera...

HDR brachytherapy procedures are usually time constrained with planning and safety checks performed immediately preceding delivery, often intraoperatively. Additionally, planning systems can be integrated with oncology information systems (OIS) or standalone...

Commercial model-based dose calculation algorithms (MBDCAs) show promise for advancing intensity-modulated brachytherapy (IMBT). However, transitioning from the TG‑43 protocol to MBDCAs requires benchmark studies against reference dosimetry. This work introdu...

To develop and validate an automated quality assurance (QA) methodology for verifying ring applicator dwell positions using kV imaging and radiochromic film, with emphasis on quantifying measurement uncertainty, reducing observer-dependent variability, and ev...

Oncology information system (OIS) and Treatment planning system (TPS) upgrades are high-impact events that require comprehensive validation. Knowing what to prepare, who to involve, and what to test on go-live day is critical for patient safety and clinical c...

Directional Modulated Brachytherapy (DMBT) tandems using tungsten shielding have demonstrated improved dose conformity versus conventional tandem-and-ring (T&R) applicators. In prior work, DMBT six-groove tandem with a standard ring reduced D2cc to rectum, bl...
