Gastrointestinal (GI) adverse events following 177Lu-PSMA radiopharmaceutical therapy (RPT) occur frequently, including nausea, vomiting, constipation, and diarrhea (occurring in 19-35% of patients). Despite the frequent occurren...

LSF derived from MAA-based nuclear medicine imaging is a standard component of 90Y-SIRT treatment-planning. Elimination of MAA-based LSF determination has been suggested in select cases to streamline 90Y-SIRT workflows and avoid...

AAPM TG Report 232 recommends deviation index (DI) action limits of ±1 and ±2 SD based on site radiographic exam data. However, obtaining DI data can be arduous and time-consuming. We propose a solution to efficiently and continu...

Iatrogenic cognitive deficits are a major concern in neuro-radiotherapy, especially in pediatric cases. Compared to X-ray treatment modalities, proton and ion beam therapies show improved sparing of cognitive functions, for which...

Ultrafast ultrasound (UFUS) enables imaging of blood flow, functional dynamics, cardiac motion, and real-time treatment verification. UFUS is often acquired using high frame-rate single plane-wave imaging (SPWI), which has limite...

This work describes the development of a flexible educational framework designed to address required curriculum and professional competencies for Radiation Oncology (RO) and Medical Physics (MP) residents implemented in two disti...

Targeted alpha therapy (TAT) produces fundamentally different dose-response behavior than beta-emitting therapy because energy deposition occurs from rare, short-ranged, high-LET particle traversals. Under typical TAT administere...

AI-based medical image segmentation has achieved strong performance across diverse tasks, yet progress remains constrained by ground truth availability. Interventional fluoroscopic angiography, a 2D modality with complex vascular...

Radiation therapy–associated cardiac arrhythmia is a clinically significant complication of thoracic RT, with important consequences for long-term cardiovascular health and treatment outcomes. Although arrhythmia risk evolves ove...

X-ray-induced acoustic (XA) imaging provides a potential solution for noninvasive, real-time 3D dose verification by characterizing the radiation-induced thermoelastic effect. However, clinical implementation is severely hampered...

The purpose of this study was to test the ability of a portable gamma camera capable of imaging gammas from 30 – 600 keV gammas to produce 3D imaging and activity quantification of radiopharmaceutical distributions for RPT verifi...

To address barriers in radiation therapy education in low resource communites by developing accessible AR/VR training modules that bring technology to learners rather than requiring access to scarce, expensive equipment.

To develop a data-efficient, unsupervised deep learning framework for deformable SPECT/CT registration that supports voxel-based dosimetry in radionuclide therapy, particularly in clinical settings with limited imaging datasets.

To demonstrate that dual-energy CBCT (DE-CBCT) on angiography systems can deliver material-specific quantitative imaging and metal artifact reduction at the point of intervention.

While Proton Acoustic (PA) imaging has shown promise for range verification, its application in complex transcranial environments remains under-explored. This study aims to demonstrate the feasibility of in situ 3D dose mapping a...

To investigate the effects of combining proton and photon radiotherapy (RT) with a DNA polymerase theta inhibitor (Polθi) on DNA damage and promotion of tumor immunogenic remodeling.

Diagnostic and Interventional Radiology Physics

Physics plan and chart review is one of the most effective QA processes to identify high-severity errors in radiotherapy treatments; mastering it is crucial for our residents. However, exposure to such errors during training is l...
