The simultaneous production of iodine-125 (¹²⁵I) and iodine-126 (¹²⁶I) during neutron irradiation directly impacts radionuclidic purity and clinical applicability of brachytherapy seeds. This study evaluated the dependence of ¹²⁵...

We aimed to optimize patient-specific quality assurance (PSQA) evaluation criteria using an electronic portal imaging device (EPID) and myQA SRS (IBA Dosimetry) to detect spinal cord Dmax deviations in spine stereotactic body rad...

To assess the impact of scanning speed on beam data quality using a novel plastic scintillation detector (PSD) compared with conventional methods, with the goal of enabling ultrafast scanning.

The BetaBox 2.0 is a high sensitivity, low noise instrument that measures positron and electron emissions from radiopharmaceuticals in single cell samples. The goal of these measurements is to elucidate the biological differences...

The CT CAP W/O CONT protocol (Computed tomography for chest, abdomen, and pelvis without contrast) is routinely scanned in patients for assessment of systemic disease, oncologic surveillance and staging. Traditionally, this proto...

To optimize virtual monoenergetic imaging (VMI) in spectral photon-counting CT (SPCCT) through material decomposition, aiming to improve soft-tissue contrast and image quality.

While MR-guided radiotherapy enables real-time, soft-tissue–based motion management, clinical 2D cine MRI often sacrifices spatial resolution to maintain frame rate, which can contrast oncological contrast. This study aims to opt...

To systematically evaluate if optimized spot-delivery patterns in pencil-beam scanning can reach FLASH-compatible dose rates (>40Gy/s) at clinically relevant fractions of 4Gy and to identify key machine and planning parameters fo...

To optimize a N-Isopropylacrylamide (NIPAM)-based polymer gel dosimeter for kilovoltage x-ray irradiations, and to demonstrate its application for 3D isocenter verification.

To create user-friendly, size and heart condition-specific protocols to improve coronary CT angiography (CCTA) image quality, reduce dose, and expand eligibility to patients with contraindications due to heart activity.

This study proposed the residual dynamic transformer-nnU-Net (RDT-nnU-Net) for automated delineation of esophageal cancer and adjacent organs at risk (OARs) in radiotherapy, aiming to improve accuracy, coverage, and adaptability...

Post-mastectomy chest-wall (CW) irradiation is well suited for proton FLASH due to the predominance of normal tissue within the target and the feasibility of single-energy tangential transmission beam (TB) delivery. This study in...

We introduce a framework to optimize administered radioligand activity by calculating DNA lethal lesions (LLs), balancing maximal tumor control with minimal normal tissue damage.

To optimize diffusion-kurtosis imaging (DKI) MRI acquisitions for improved time efficiency while preserving quantitative data fidelity, enabling the future integration of DKI into cancer-care workflows for RT treatment planning a...

To assess how ridge filter (RF) and range shifter (RS) composition, along with pin spacing, shape, and lattice arrangement, influence in-field dose rates, dose uniformity, and field penumbra widths during ultra-high dose rate pro...

To develop and evaluate a voxel-based straight-line trajectory planning framework for CT-guided lung biopsy that enables safe and efficient pre-procedural identification of needle paths while minimizing risk to organs at risk (OA...

FLASH radiotherapy (FLASH-RT) has emerged as a promising technique that delivers radiation at ultra-high dose rates (UHDR), which significantly spares normal tissues while still effectively controlling tumors, referred to as the...

To investigate the optimal wall thickness for a Rexolite beam pipe for a proof-of-concept dielectric wall accelerator (DWA). In a DWA, protons are accelerated by a virtual traveling wave, created by switching electric fields alon...

To determine the optimal X-ray beam quality by varying the copper (Cu) filter thickness for upright, cone-beam breast CT (CBBCT) to achieve a mean glandular dose (MGD) of approximately 4.5 mGy that is suitable for breast cancer s...

Limiting jaw position across midline is a common inverse-planning strategy to minimize dose to normal tissue and improve conformality when treating irregular targets. However, jawless linacs lack an analogous, planner-controlled...

Accurate small‑field dosimetry is strongly influenced by detector volume averaging, density effects, and perturbations. Solid‑state detectors such as microSilicon and microdiamond are widely used due to minimal correction require...

To evaluate the uses of beryllium oxide optically stimulated luminescent dosimeters (OSLDs) and solid-state micro-diamond detectors as viable dosimetry tools for ultra-high dose rate electron FLASH treatments.

Training nnU-Net models for medical image segmentation with large patient samples is computationally expensive, limiting iteration speed in research and clinical translation. We present an optimized training workflow that signifi...

Conventional 3D CT-CBCT registration is typically performed independently at a single respiratory phase, limiting the ability to characterize 4D respiratory motion and temporal continuity between planning and treatment. This work...
