Direct-to-unit (DTU) adaptive radiation therapy (ART) is an emerging workflow that reduces treatment delays for urgent radiation therapy by eliminating the need for a separate simulation scan. Despite increasing clinical adoption...

Magnetic resonance imaging (MRI) is an important tool for visualizing tumor sites and organs at risk during spine radiation treatment planning. Some people with spinal metastasis require pedicle screw fixation to stabilize the sp...

Deep inspiration breath hold (DIBH) using surface guidance can be useful as a motion management strategy but for high dose, steep gradient modalities such as SBRT, it is important to compliment it with active motion management us...

Monte Carlo (MC) particle transport methods which with high computational cost of MC simulations severely limits their efficiency of BNCT dose calculations. We developed a physics-informed neural network (PINN) framework for effi...

Implicit neural representations (INRs) enable continuous, resolution-agnostic modeling of complex anatomical motion and have shown remarkable promise for deformation-driven, instance-specific real-time volumetric MRI estimation f...

To auto-classify radiation oncology safety events reported in narrative descriptions using a large language model (LLM) and propose a framework for future AI-assisted reporting systems.

Proton pencil-beam scanning (PBS) FLASH radiotherapy requires dosimetry systems capable of accurate and reliable operation under ultra high dose rate (UHDR) conditions. Faraday cups (FC) and multi-layer Faraday cups (MLFC) are do...

The University of Mississippi Medical Center (UMMC) underwent a major clinical transition in 2025-2026, which included Machines: Decommissioned 2 external beam devices and 1 CT simulator Replaced with 2 new external beam devices...

To develop a practical and simple method for estimating beam-on delay associated with respiratory-gated radiotherapy and validating the accuracy of the estimated delays

Linear accelerator (LINAC) coordinate system conventions have historically evolved heterogeneously, with vendors and institutions adopting mixed non-IEC standards. While clinically functional, this lack of uniformity introduces a...

To develop a simple process for reliably detecting and quantifying the presence of the long-lived contaminant Lu-177m (t ½ = 160 d) in Lu-177-based therapeutics.

In proton therapy treatment planning, several free parameters impact both plan quality and delivery time. These include spot and energy layer spacing, MU per spot or layer, and in some systems, utilization of adaptive apertures (...

To quantify the impact of Region of Interest (ROI) selection on the localization accuracy, latency, and stability of a commercial SGRT system. This preliminary phantom study follows AAPM TG-302 guidance to investigate how the geo...

To explore a comprehensive pre-therapeutic dose prediction workflow for Lu‑177‑PSMA radiopharmaceutical therapy by combining a physiologically based pharmacokinetic (PBPK) model with Monte Carlo simulation.

[To investigate the clinical accuracy and feasibility of markerless optical-guided self-positioning for breast cancer patients undergoing radiotherapy.]

CT reference levels are mandated by Texas state regulations, and Medical Physics is responsible for reviewing CT studies that exceed these levels and determining the cause. The current clinical reference level for body CT, 60mGy,...

To propose a clinically relevant, quantitative comparison of low-contrast edge definition on routine CT Head examinations.

For proton spots to be deliverable, the intensity of each spot must either be zero or exceed a specific minimum monitor unit (MMU) threshold, which is a nonconvex problem. This study develops a quantum computing (QC)-based optimi...

Beam angle optimization (BAO) is a critical component of radiation therapy (RT) treatment planning, particularly for proton therapy, where small variations in beam configuration can substantially affect plan quality. BAO is natur...

Planners must often choose how to cluster multiple SRS/SRT targets without reliable a priori dosimetric prediction, making exhaustive plan-and-optimize testing impractical in complex cases. A previously developed target-clusterin...

To report a rare failure of a sealed source Cesium-137 E-Vial used for dose calibrator quality control, describe the methods used for detection and characterization of the leak and emphasize implications for radiation safety, sou...

Conventional approaches to PET spatial resolution assessment, such as the American College of Radiology (ACR) guideline and the NEMA NU 2-2018 protocol, offer limited insight into the effective spatial resolution achieved under c...

To experimentally quantify the mechanical delivery errors of a pre-clinical Dynamical Collimation System (DCS) prototype for intensity modulated proton therapy (IMPT) and evaluate the dosimetric impact of these errors to the targ...

Approximately 80% of clinically actionable oncology data remains siloed in unstructured formats, including clinical narratives and pathology reports. This study validates an end-to-end Natural Language Processing (NLP) pipeline f...
