Measurement based QA is required in clinical practice due to the delivery complexity of IMRT. Many factors can affect measurement accuracy and QA passing rate. In this study, we aimed to investigate the impact of beam hardening a...
In proton therapy with pencil beam scanning (PBS), repainting mitigates respiratory motion effects but increases treatment time, burdening patients who must remain on the couch for extended periods. To address this challenge, we...
To confirm leaded brass as a shielding alternative to Cerrobend for eye shields during total-skin electron (TSE) radiotherapy treatments.
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...
To calculate the minimum viable sequencing parameters needed to detect radiation-induced mutations using single-cell whole-genome DNA sequencing.
To assess the accuracy of empirical relative biological effectiveness (RBE) models in predicting variations in intrinsic radiosensitivity using a comprehensive dataset of clonogenic cell survival.
Patients who undergo stereotactic body radiation therapy (SBRT) for lung cancer can present with contraindications, making it difficult to achieve tumoricidal coverage and adequate organs-at-risk (OAR) sparing. MRI guided-adaptiv...
To investigate whether unedited organs at risk (OARs) automatically segmented by Artificial Intelligence-based algorithms can be used by inverse optimizer to generate plans for lung SBRT cases such that the plans are still clinic...
To provide practical guidelines for imaging dose optimization and establishment of dose reference levels for CBCT in radiation therapy. Such guidelines are essential to ensure adherence to ALARA principles without compromising pa...
Small animal irradiator radiation measurements for kV x-rays typically use in-air absolute dose rate calibration and film in solid water for planar dose distributions. Using water as a medium provides a close representation of so...
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...
Mechanistic models can help us understand why hadrons kill cells more effectively than photons. We used ChronoRepair, an agent-based model that tracks individual double-strand breaks (DSB) through detection, repair, and cell-fate...
To assess the clinical feasibility, accuracy, and patient comfort benefits of a fully maskless workflow for head and neck (H&N) radiation therapy using Surface Guided Radiation Therapy (SGRT) for setup and intrafraction motion ma...
To evaluate the performance of the MVision AI contouring solution. The geometric accuracy and dosimetric impact of the MVision contours were assessed against the clinically approved contours for head and neck (H&N) and prostate r...
The primary objective of this study is to evaluate the clinical application of the ROSA robotic system in facilitating high-precision interstitial applicator placement for patients with Glioblastoma Multiforme (GBM), ensuring tar...
This study evaluates the clinical integration of dual-energy CT (DECT) into radiation therapy workflows. The investigation focuses on image quality, the Hounsfield Unit (HU) accuracy of virtual monoenergetic images (VMIs), and th...
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...
To clinically validate log file–based patient-specific quality assurance (PSQA) for IMRT and VMAT treatments as an efficient alternative to physical measurement-based methods, while maintaining compliance with AAPM recommendation...
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...
To validate a planning-quality HyperSight iCBCT protocol on a C-arm LINAC for head and neck (HN) offline adaptive planning. By enabling direct use of high-quality CBCTs for re-planning, this approach aims to streamline the offlin...
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...
As treatment planning evolves toward patient-specific optimization, traditional static dose constraints are insufficient for distinguishing high-quality versus acceptable plans. Current planning directives rely on generic dose co...
To develop an optimization procedure of spot weight and ridge filter (RF) dimension for single-energy proton pencil beam and apply it to a water phantom with a square-shape target in the center (prescription dose 50 Gy).
