In prostate-specific membrane antigen (PSMA)-targeted radiopharmaceutical therapy for metastatic castration-resistant prostate cancer, salivary glands often receive unintended high absorbed doses and are considered dose-limiting...

To characterize the microsecond-scale dynamics of the free induction decay (FID) of a 0.35T Magnetic Resonance (MR)-guided Linear Accelerator (MR-Linac) during irradiation.

To quantify dose delivered from a scanning microbeam x-ray irradiator using partial-volume techniques with thermoluminescent dosimeters (TLD-100) chips and to improve dosimetry in systems with small fields.

Proton arc therapy (PAT) holds promise for enhancing plan conformity while minimizing dose sparing. However, PAT faces practical barriers related to delivery inefficiency, and its effectiveness can be compromised by beam range an...

To evaluate the feasibility of delivering minibeam spatially fractionated radiation therapy (SFRT) using a novel, low-cost, dual-robot system, the Kilovoltage Optimized AcceLerator for Adaptive therapy (KOALA).

The NRC reported that between 2015 to 2024 nearly 50% of Medical Events were Y-90 related. In our institution we started using SPECT/CT 3D images from 99mTc-MAA mappings to determine target delineation, and extrahepatic shunting...

Monte Carlo (MC) simulations are the gold standard in high dose rate brachytherapy (HDR-BT) dosimetry, offering accurate dose-to-medium calculations beyond the dose-to-water calculations used clinically. However, clinical adoptio...

Current multi-leaf collimator (MLC) quality assurance (QA) methods based on the picket fence (PF) test are affected by radiation scatter from strip beams, which may reduce analytical accuracy. This study aims to quantify the impa...

To develop and validate a modality-aware cross-modal transformer for joint fusion in relapse-free survival prediction in HPV-associated oropharyngeal cancer (OPSCC), integrating PET/CT imaging and clinical data for risk stratific...

Stereotactic arrhythmia radiotherapy (STAR) is an emerging treatment for ventricular tachycardia (VT) that uses radiation to modulate cardiac electrophysiology (EP) and reduce VT. Registering radiation planning 3D imaging to card...

Ion beam radiotherapy (helium and carbon) has opened new frontiers for FLASH research by introducing LET as a critical physical parameter for mechanistic investigation. However, current FLASH effect models are restricted to low-L...

Radiation-induced lymphopenia (RiL) is linked to impaired anti-tumor immunity and poorer outcomes in thoracic malignancies. Reducing dose exposure to circulating lymphocytes (CLs) could therefore mitigate RiL. Because Intensity M...

Differences in biological effects among radiation qualities arise from variations in the spatial distribution of initial DNA damage and subsequent repair processes, both are closely linked to chromatin organizations. This study a...

Radiation induced bowel toxicity is challenging for abdominal SBRT due to proximity to PTV and high dose/fraction. Remote magnetic navigation systems (RMNS) have been developed for magnetic capsule endoscopy, in which the RMNS mo...

Localization and modernization of existing open source tools important to the medical physics community are important contributions to keeping care costs low and quality high. QATrack+ is a modern, open source, Quality Management...

It is well established that radiation can damage electronic medical devices; however, there is little guidance for managing spinal cord stimulators (SCS) in the radiation oncology setting. Total body irradiation therapy (TBI) pre...

To quantify energy- and size-dependent HU shifts in PCCT monoenergetic imaging and their impact on fat–liver separability.

Ultra-high dose-rate (>40 Gy/s) or “FLASH” radiation therapy has the potential to improve cancer treatment through reduced radiation side effects. The purpose of this work is to create and validate a particle phase space for an e...

High-pitch dual-source acquisition (“FLASH”) with tin spectral filtration has substantially reduced radiation dose while minimizing patient motion, both of which are particularly important for pediatric imaging. However, in adult...

Boron Neutron Capture Therapy (BNCT) centers are rapidly increasing worldwide due to recent clinical trials and accelerator-based neutron irradiation systems. However, unlike external photon irradiations, BNCT lacks real-time neu...

Background: Comparative studies show that at kilovoltage energies, EGSnrc and Geant4 can differ by several percent in ionization chamber response, particularly in small air cavities and steep dose gradients. These discrepancies a...

To simulate prostate treatment plans with Monte Carlo (MC) and compare with dose calculations from RayStation 11B (RS-11B) treatment planning system (TPS) for a 0.5 T bi-planar inline Linac-MR (LMR).

Estimate impact of setup and motion uncertainties on dosimetry of SRS with Virtual Cone (VC) and evaluate a simple method to account for such uncertainties in clinical dose calculations.

Monte Carlo (MC) dose calculation is the gold standard for CyberKnife radiotherapy, but its clinical integration is hindered by prohibitive computational latency. We proposed a physics- and spatially-informed diffusion model with...
