Accurate prediction of radiation-induced toxicity is crucial for optimizing radiotherapy outcomes. However, most existing predictive models rely on uni-modal data and deterministic models that are vulnerable to label noise and un...

High dose-rate brachytherapy (HDR-BT) is an essential component of cervical cancer treatment. While deep learning has shown promise to automate tasks within HDR-BT, such as segmentation of organs-at-risk (OARs) and targets, quali...

State-of-the-art recommendations for tumor response assessment are defined by the Response Evaluation Criteria in Solid Tumors (RECIST), which rely on the tumor axial long and short axes measurements. However, RECIST-based measur...

This work applies the TG-51 kQ formalism to energies below Co-60 in determining beam quality conversion factors (kQ) for thimble ionization chambers in HDR brachytherapy. The sensitivity of calculations to source-to-detector dist...

Radiopharmaceutical therapy (RPT) delivers targeted radiation to cancer cells. Patient‑specific dosimetry can help estimate dose and predict treatment outcome. However, tumor segmentation approaches vary across institutions, intr...

Overlapping tracks complicate particle classification and are unavoidable in pixelated semiconductor detectors due to their random nature. This study introduces a Hybrid Particle Track (HPT) net and a Simultaneous Track Energy An...

The Mevion S250-FIT is the world’s first ultra-compact proton therapy system designed with a form factor compatible with existing LINAC vaults. This raises questions regarding radiation shielding adequacy and electromagnetic comp...

To develop an acetylshikonin/galunisertib dual-drug core–shell Gel/PCL nanofibrous membrane for radiation-induced skin injury.

To evaluate whether signed distance field regression improves geometric fidelity in intracranial vessel segmentation from non-contrast vessel wall imaging (VWI).

To develop a fast and scalable computational framework for estimating DNA damage induced by X-ray irradiation while retaining track-structure fidelity and reducing computational cost.

Magnetic resonance (MR) imaging is routinely used to contour targets for stereotactic radiotherapy planning. However, MR images can suffer from susceptibility-induced geometric distortions, especially near air-tissue interfaces....

Large-animal studies of stereotactic arrhythmia radiotherapy (STAR) are faced with financial and logistical difficulties that limit widespread implementation. We developed a single-platform STAR porcine workflow on an O-ring lina...

HyperSight cone-beam CT (CBCT) has been validated for direct treatment planning without needing conventional CT simulation. We propose a simulation-free whole-brain radiotherapy (WBRT) workflow using the Ethos online adaptive pla...

Simulation-free-radiation-therapy (SFRT) could improve patient access, efficiency, and clinical throughput for benign indications such as knee osteoarthritis. For sites with limited geometric complexity and inter-patient variabil...

To explore the potential of diffusion-weighted spectroscopy to estimate lipid droplet diameter with short acquisition times (< 30 s).

Efficacy, feasibility, and safety of extracranial, single-fraction MR-guided adaptive radiotherapy (SMART-1fx) was reported in the SMART ONE trial (NCT04939246). This work evaluates SMART plan quality relative to RTOG-0813 standa...

Lung cancer cases frequently involve multiple lesions, and treatment with a single isocenter can introduce geometric uncertainties, particularly due to inter-fraction motion. Online adaptive radiotherapy (ART) offers a strategy t...

To evaluate the Size Specific Dose Estimate (SSDE) based on the AAPM report TG-293 for pediatric head CT, and to propose local diagnostic reference levels (LDRLs) in the Canadian province of Nova Scotia.

Low muscle quantity, defined by computed tomography (CT)-based skeletal muscle index (SMI), is emerging as a predictor of clinical outcomes in patients with HNC. This study aims to evaluate whether CT-defined SMI is associated wi...

To compare our clinical skin flash method, based on MLC openings on a fictitious swelling volume, with the robust optimization approach available in RayStation version 2023B.

Large variation up to 8% in field output factor (FOF) among various investigators has been reported. This is critical for modern radiotherapy techniques. Field definition based on FWHM (Sclin) and S (jaw based) has been used but...

Total Body Irradiation (TBI) for patients with hematological malignancies aims to deliver a prescribed dose within ±10% to the entire body as conditioning for bone marrow transplantation. Existing TBI techniques are often complex...

To develop and validate an automated quality assurance (QA) methodology for verifying ring applicator dwell positions using kV imaging and radiochromic film, with emphasis on quantifying measurement uncertainty, reducing observer...

Ultra-high Dose-Rate (UHDR) radiotherapy challenges conventional dosimetry methods. Optical calorimetry (OC) enables direct, dose-rate-independent measurement of spatially and temporally resolved dose-to-water distributions. This...
