Therapy Physics

Glioblastoma has a low median survival of 3cm from the tumor, where deformation is minimal. Vessels 80% of patients. Future work will incorporate this pathway into a full front-to-end deformable registration approach to precisely...

Xerostomia is a common toxicity after radical head and neck cancer (HNC) radiotherapy (RT), causing long-term quality-of-life impairment. Although salivary function may recover, dose–response relationships governing long-term rec...

Understanding of medical physics is essential for safe and effective radiation oncology practice. This study evaluates current instructional practices for physics education in radiation oncology physician residency programs follo...

Diagnostic and Interventional Radiology Physics

Education is a core professional responsibility for medical physicists, yet most receive limited formal training in pedagogy or instructional design. Recognizing this gap, the American Association of Physicists in Medicine (AAPM)...

To develop a pixel-level uncertainty-aware consistency (UA-Cons) learning framework to optimize the feature compensation behavior of deep neural networks in scenarios where multi-parametric MRI modalities are incomplete.

Radiation-Induced-Lymphocyte-Kill (RILK) varies substantially among patients and the extent to which different factors contribute to RILK remains incompletely understood. We present a model to predict time-dependent RILK for adva...

Radiopharmaceuticals, Theranostics, and Nuclear Medicine

Persistent difficulty in recruiting therapeutic medical physicists, particularly outside large metropolitan and/or academic centers, suggests a geographic mismatch between training locations and workforce demand. While residency...

Therapy Physics

Tumor growth and response to radiotherapy (RT) is a multiscale biological process encompassing cellular dynamics, extracellular transport, vascular and immune modeling. This work develops a comprehensive simulation platform to mo...

Non-invasive diagnosis of pulmonary nodule invasiveness via CT imaging is critical for clinical management. However, assessing the status of medium-sized nodules (10-20 mm) remains a significant challenge for both radiologists an...

Although radiographic exposures are individually low dose, in 2016 there were 275 million in the U.S.; the broad population makes consistent dose and image quality important. A large institution faces significant challenges to ac...

To characterize patient‑specific quality assurance (PSQA) measurement frequency patterns across Canadian radiotherapy centers and to identify factors associated with reduced PSQA measurement frequency for routine VMAT and SBRT de...

Stereotactic body radiation therapy (SBRT) has been shown to be an effective treatment for hepatocellular carcinoma associated with lower rates of severe toxicity because of treatment. However, SBRT for liver carcinoma can still...

Micro-ultrasound (microUS) provides high-resolution visualization of the prostate for interventional procedures; however, the scarcity of annotated datasets limits the development of robust automated segmentation methods. This st...
