To assess the effectiveness of SVD-based denoising on the brain Diffusion Weighted images acquired from a 0.35T ViewRay Magnetic Resonance Linac (MRL) and enhance the image quality while preserving the diffusion information.

Limiting contralateral breast dose (CBD) is an important concern in breast radiotherapy, as prior studies link doses >1Gy to significantly increased secondary cancer risk. Furthermore, complex beam geometry increases low-dose irradiation of healthy tissue whi...

To develop a global database of medical physics initiatives in support of a sustainable and equitable collaborative ecosystem that minimizes resource duplication and inefficiencies across stakeholders.

Persistent difficulty in recruiting therapeutic medical physicists, particularly outside large metropolitan and/or academic centers, suggests a geographic mismatch between training locations and workforce demand. While residency programs have expanded nationa...

Stark global inequities persist in access to radiological health services, with low- and middle-income countries (LMICs) bearing an increasing cancer burden while facing critical shortages in trained medical physicists and radiation oncologists. Virtual educa...

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 dose-rate-independent charge col...

A custom optimization engine was developed to determine the optimal collimator and couch angles for single-isocenter, multi-lesion LINAC-based stereotactic radiosurgery (SRS). Herein, we demonstrate technical feasibility of the tool within the Eclipse treatme...

To develop a reliable batch‑calibration method and dose‑reading protocol for in-vivo scintillation imaging dosimetry during radiation therapy.

Cherenkov imaging provides valuable beam delivery information, but fixed treatment camera positions are subject to gantry occlusions and couch rotation artifacts that inhibit imaging for a significant percentage of clinical cases. To overcome these limitation...

Magnetic resonance spectroscopic imaging (MRSI) provides spatially resolved metabolic information but remains constrained by long acquisition times, particularly for X-nuclei applications with low sensitivity. Parallel imaging methods such as GRAPPA have been...

Malawi, a low-income country in southeastern Africa with a population of more than 20 million, historically lacked access to public radiotherapy services. In July 2025, the country’s first public radiotherapy program became clinically operational at Kamuzu Ce...

FLASH radiotherapy delivers curative dose to tumor at ultra-high dose rates (UHDR,>40Gy/s) while mitigating normal tissue toxicity. However, data on late-responding tissues are limited, halting its safe clinical translation. Owing to its steep dose–response a...

To validate and deploy a complete applicator-specific phase space file library for the GMV Radiance treatment planning system, establishing the first clinically ready Monte Carlo-based treatment planning system (TPS) for electron FLASH radiotherapy.
