Leptomeningeal metastases (LM), or the spread of cancer to the cerebrospinal fluid, is a neurologically devastating manifestation of cancer. Without treatment survival is limited to months, and few effective therapies exist. A ra...
To develop a quantitative plan quality scoring (PQS) tool for evaluation of left-sided breast radiotherapy plans and to compare performance across four platforms.
To evaluate a quantitative SGRT-based workflow for pre-imaging DIBH amplitude verification and quantify its impact on setup precision by comparing residual setup errors across the VRT, LNG, and LAT axes.
Prone breast treatment is a known approach in radiation therapy. In addition to the benefits in lowering the OAR dose, an MRI imaging to guide preoperative radiation can be used. A fixed beam Proton PBS using a flat table top wit...
Mammography (compressed 2D) and MRI (uncompressed 3D) capture breast tissue under different conditions, complicating tumor localization across modalities. To bridge this gap, we developed a customizable physical platform to simul...
While optically stimulated luminescence dosimeters (OSLD) offer advantages in reusability and efficiency, they overestimate the surface dose due to thick effective point of measurement. The aim of this study is to investigate the...
Jaw-tracking is a standard feature for IMRT and VMAT on TrueBeam accelerators, but its application in 3D-conformal radiotherapy (3D-CRT) is less common. Benefits may exist when utilizing electronic compensation. This study evalua...
Standard in-house techniques for evaluating anatomical changes during radiation therapy often involve manual contouring, neglecting internal organ motion, deformation, or weight-induced volume loss. These limitations potentially...
Open-source software offers a transparent and cost-effective alternative to commercial, patient-specific quality assurance (PSQA) systems; however, clinical validation remains essential. This study aims to validate open-source Py...
To perform a dosimetric comparison of Intensity-Modulated Radiation Therapy (IMRT) plans generated using Varian C-arm linear accelerator (LINAC) and Radixact Helical TomoTherapy (TOMO) for breast cancer patients with highly compl...
To evaluate patient-specific quality assurance (PSQA) measurements across 18 disease sites treated with intensity modulated proton therapy (IMPT) from January 2024 through August 2025.
Hybrid tangential breast radiotherapy commonly uses a high proportion of open fields to enhance robustness against inter-fraction anatomical variation, potentially limiting planning flexibility. In five-fraction hypofractionated...
This study seeks to understand the relationship between bolus thickness and dose coverage for the treatment of post-mastectomy breast cancer patients. With the advent of novel bolus materials and 3D printing, it is possible to us...
Proton therapy for breast cancer presents unique dosimetric challenges due to frequent use of range shifters and potential proton penetration into lungs. The study aims to compare dosimetric results between a novel proton treatme...
To assess the dosimetric impact and planning efficiency of EZFluence integrated into the Monaco treatment planning system compared with conventional planning in breast-conserving radiotherapy.
Adjuvant radiotherapy following breast-conserving surgery or mastectomy reduces recurrence and improves survival of breast cancer patients. Left-sided breast radiotherapy, however, increases the risk of radiation-induced heart to...
VMAT post-mastectomy and regional lymph node irradiation is a highly complex technique that requires multiple planning iterations to achieve adequate coverage while minimizing OAR doses. RapidPlan, a Varian knowledge-based modeli...
The accuracy of surface-guided radiation therapy (SGRT) depends on reliable optical surface tracking, which varies with surface geometry. This study evaluates a widely‑used commercial SGRT system by measuring its tracking perform...
Accurate patient positioning is critical in proton therapy, where range uncertainties increase sensitivity to setup errors; therefore, cone beam computed tomography (CBCT) is routinely used for image guidance. However, it also in...
To assess the clinical implementation, contour accuracy, and workflow efficiency of a commercially available deep learning auto-contouring system for CT-based radiotherapy planning across multiple anatomical sites.
Accelerated partial breast irradiation (APBI) combined with online adaptive radiotherapy (OART) offers precise treatment of early-stage breast cancer, but inter-observer variability (IOV) in target delineation must be accounted f...
Metastatic reactivation—the transition of dormant cancer cells into active, proliferative lesions—drives late cancer recurrence in many survivors. In breast cancer, up to 30% of patients develop distant metastases 5–25 years afte...
Monte Carlo (MC)-based treatment planning system (TPS; RayStation, RaySearch laboratories) and 3D secondary dose check software (VeriQA RT Montecarlo 3D, PTW) were commissioned and benchmarked against well-established TPS. This s...
Conventional radiotherapy plan evaluation relies on isolated dose–volume metrics that provide limited insight into the magnitude and clinical significance of deviations from protocol-defined organ-at-risk (OAR) objectives. We pro...
