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 following the release of the AAPM/A...

To create a simple web application for collecting quality control data from computed tomography systems that provides basic analytics and manages physicist approvals.

To develop a simple process for reliably detecting and quantifying the presence of the long-lived contaminant Lu-177m (t ½ = 160 d) in Lu-177-based therapeutics.

To characterize the angular dependence of the Elekta Gamma Knife Esprit High Definition Motion Management (HDMM) system and examine the feasibility of non-standard camera angles for the treatment of larger patients.

HDR gynecologic brachytherapy can involve creating a new plan for each fraction of treatment or delivering a single plan for both fractions of an implant. This work retrospectively analyzes the differences in EQD2 doses to the CTVs and OARs between two planni...

Spatially fractionated radiation therapy, specifically grid radiation therapy(GridRT),is a treatment option for bulky tumors.VMAT GridRT utilizes modulated arcs to create the grid of spherical targets within the tumor.This study evaluates optimization paramet...

Neck CT protocols often present challenges for objective lesion detectability tasks. We systematically assessed lesion detectability in clinical scans to identify quality gaps and dose utilization inefficiencies.

Simple clinical criteria for deep inspiration breath-hold (DIBH) eligibility in left-sided whole-breast radiotherapy, such as the ability to sustain a 20-30 second breath-hold, are commonly used but do not reliably predict dosimetric benefit. Robust assessmen...

To evaluate neck CT image quality (IQ) and dose efficiency for lesion assessment across multiple scanners, identifying scanner-level differences and protocol optimization opportunities.

Determine if linguistic differences are present in letters of recommendation (LOR) for applicants to medical physics residency programs (MPRPs).

To develop a compact fluoroscopy scatter “signature” that predicts net scatter Air-Kerma rate at staff locations as a function of patient-equivalent thickness, distance, and angular position using routine measurements.

Manual background selection for contrast-to-noise ratio (CNR) calculations in CT image quality assessment is time-consuming, operator-dependent, and introduces >15% measurement variability that compromises reproducibility. Advanced metrics such as Noise Power...
