Based on measured failure data and adverse event records from five sentinel hospitals, this study compares failure characteristics of medical electron linear accelerators (LA) across brands, regions and service life, clarifies co...

This study addressed class imbalance in automated pleural mesothelioma segmentation and demonstrated that addressing this imbalance significantly improves agreement in the optimal probability map threshold, enabling simultaneous...

Preclinical studies with small animals require precise control to yield conclusive results. Small animal irradiations differ from clinical irradiations and can push dose calculation algorithm to their limits: small volumes, small...

A novel in vivo method to monitor bone cancer during particle therapy that uses prompt gamma-ray spectroscopy (PGS) to quantify bone density and calcium (Ca) content. Upon bone irradiation with a particle beam, Ca-specific gamma...

We present a small-animal SPECT-CT system based on CZT imaging spectrometers and a rapidly switchable dual-FOV apertures. The system supports both total-body imaging and focused, high-resolution imaging. These capabilities addres...

This work reports the development and initial results from irradiations of IROC’s TBI anthropomorphic phantom.

Endobronchial Valves (EBV) are one of the few treatment options for patients with moderate to severe emphysema. Eligibility is typically assessed from CT image data analysis including Emphysema Score (RA950) and Fissure Integrity...

Conventional intensity-modulated proton therapy (IMPT) planning commonly relies on fixed, uniformly distributed spot grids with optimization restricted to spot weights. Although adaptive spot placement has been explored to improv...

Population-level CT dose monitoring typically relies on summary statistics and benchmark comparisons, which can obscure distributional features such as multimodality and disproportionate upper tails. This preliminary feasibility...

Hyperpolarized chemical exchange saturation transfer (HyperCEST) MRI using 129Xe gas enables detection of signal loss from perfluorooctyl bromide nanodroplets (PFOB NDs). We developed a kinetic model for 129Xe HyperCEST that enab...

Stereotactic Body Radiation Therapy (SBRT) has gained attention for the treatment of patients with refractory ventricular tachycardia (VT). VT substrates are complex, multifocal, progressive, and may require urgent treatment. As...

To apply label-free multimodal nonlinear optical (NLO) imaging including stimulated Raman scattering (SRS) and two-photon excitation fluorescence (TPEF) microscopy for multiplex single-shot identification of metabolic biomarkers...

To develop and validate an agentic AI framework using Model Context Protocol (MCP) that enables clinicians to control CT-MR image registration through natural language guidance. The study aims to determine if text-based clinical...

Adaptive radiotherapy (ART) decisions made during quality assurance CT (QACT) review are commonly documented in free‑text clinical notes. Automated classification of these rationales could enable large‑scale workflow and quality‑...

Magnetic resonance imaging-guided online adaptive radiotherapy (MRgRT) requires a complex planning process, during which an upstream peer review prior to physician approval plays an essential role in early error detection and sup...

Acute urinary pain is common after prostate stereotactic body radiotherapy (SBRT). Although treatment breaks and bladder filling protocols are adopted to mitigate toxicity, evidence supporting these interventions is limited. We i...

To evaluate real-time, longitudinal performance of a commercial auto-segmentation model across a broad radiotherapy cohort and examine contour editing influence on planning decisions and organ-at-risk (OAR) doses, with attention...

Head-and-neck cancer (HNC) treatment planning is challenging due to the close proximity of multiple critical organs-at-risk (OARs) to complex target volumes. Intensity-modulated carbon-ion therapy (IMCT) is attractive for HNC due...

To determine, for three common cancers, if in vitro α/β estimates agree with clinical values, and if there are a common pattern of discrepancies.

Upright radiotherapy offers favorable physiological and geometric conditions compared with conventional supine delivery. However, posture-induced anatomical deformation complicates the alignment of supine diagnostic images with u...

Lattice radiotherapy (LATTICE) is a spatially fractionated technique that delivers high doses to discrete peak regions within the target while maintaining lower doses in surrounding valley regions, yielding a high peak-to-valley...

Lattice radiotherapy (LRT) is a spatially fractionated radiation technique that creates three-dimensional arrays of high-dose vertices within tumor volumes. Current LRT implementations face geometric constraints in small and medi...

Teaching medical physics to radiation oncology residents is challenging, given their limited foundational training in physics, competing clinical demands, and inconsistent motivation beyond preparation for the ABR physics examina...

To develop and validate a female pelvis-specific deep learning deformable image registration (DIR) framework optimized for longitudinal CT imaging, enabling accurate dose accumulation and cumulative dose assessment in gynecologic...
