Secondary electron range constrains standard 6MV radiotherapy to 80%-20% dose penumbra of ~2.4–3 mm, limiting conformity and organ sparing. Photon FLASH likely necessitates even larger penumbra, which is potentially problematic a...

Protoacoustic (PA) imaging enables real-time verification of proton dose deposition by reconstructing 3D initial pressure maps from acoustic signals generated during proton delivery. However, in practical treatment settings, dete...

Measuring and monitoring dose and noise for each patient exam has been proposed as part of a quality program for routine CT practice. Mathematical model observers have been recognized as more meaningful methods than noise level a...

To evaluate tumor oxygenation response to hyperbaric oxygen therapy using oxygen-enhanced MRI (OE-MRI) and assess whether elevated oxygen partial pressure can convert hypoxic, radiation-resistant tumor regions to a more radiosens...

Ultra-high dose-rate (UHDR) radiotherapy has been reported to reduce normal tissue toxicity compared to conventional dose-rate irradiation (CDR), yet objective, quantitative imaging markers associated with this effect remain limi...

To evaluate whether MR-based electrical conductivity imaging can distinguish glioma phenotypes with varying aggressiveness and to investigate the metabolic origins of conductivity differences in glioma cell models.

Automated segmentation of lung nodules in chest CT is critical for early cancer screening but remains challenging due to the small size and variable morphology of nodules, which often resemble vessels or pleura. This study propos...

Accurate evaluation of multi-modality deformable image registration remains a critical challenge in radiotherapy. Traditional metrics such as Normalized Mutual Information (NMI), Mean Absolute Error (MAE), and Normalized Cross-Co...

FLASH radiotherapy (FLASH‑RT) employs ultra‑high dose rates (UHDR) that preferentially spare normal tissues relative to conventional dose‑rate radiotherapy (CONV‑RT) while maintaining tumor control, this is known as the FLASH eff...

FLASH radiotherapy, defined by ultra-high dose rates (UHDR; >40 Gy/s), can reduce normal-tissue toxicity while maintaining tumor control, yet reported FLASH effects show substantial variability across experimental and preclinical...

To study the cardiac and respiratory heart motion together. Cardiorespiratory motion management is a significant topic in stereotactic arrhythmia radiotherapy (STAR). Cardiorespiratory motion consists of the heart beating and res...

MRI scanners contribute substantially to healthcare energy use, yet quantitative benchmarks at the exam- and pulse sequence-level are limited. The purpose of this work was to develop an automated framework for MRI energy quantifi...

Targeting accuracy in stereotactic ablative body radiotherapy (SABR) for hepatocellular carcinoma (HCC) is often hindered by the poor soft-tissue visibility of tumors on standard image-guided radiotherapy using kilovoltage (kV) i...

Therapy Physics

Robust and quantitative treatment planning remains a critical barrier to reproducible preclinical FLASH radiotherapy (FLASH-RT) research. We developed and validated a Monte Carlo–based treatment planning interface (TPI) for elect...

Prostate MRI is increasingly used in modern radiotherapy, but compared with CT, large-scale MRI datasets remain limited for fine-tuning foundation models. This study investigates the cross-modality transferability of a CT–fine-tu...

To address severe boundary artifacts in Electrical Properties Tomography (EPT) reconstruction caused by noise amplification and erroneous numerical differentiation across tissue discontinuities. A unified, boundary-aware reconstr...

To test whether a physics-informed “time-machine” tumor synthesis pipeline can generate realistic small pancreatic ductal adenocarcinoma (PDAC) targets on contrast-enhanced CT for training and stress-testing AI models intended to...
