This study assesses whether log-file based patient-specific QA can reliably substitute for measurement-based QA by evaluating correlations between detector-based and log-file based gamma pass rates across multiple plan types and...

Accurately identifying clinically significant prostate cancer (PCa) lesions remains a difficult task. Although tumor characteristics associated with false-negative lesions have been investigated, the potential radiologist search...

Standard glioblastoma (GBM) radiotherapy planning uses uniform margins to expand the gross tumour volume (GTV) to the clinical target volume (CTV) and planning target volume (PTV). This approach does not account for patient-speci...

The purpose of this work was to optimize the radiotherapy treatment planning workflow for cervical cancer using artificial intelligence-based tools and optimization trough scripts, with the goal of reducing planning time and impr...

Accurate radiation dosimetry is critical for patient safety and treatment quality in radiotherapy. Conventional thermoluminescent dosimeters have limitations in re-readability and flexibility. This study aims to explore ZnSe nano...

Sparse-view cone-beam computed tomography (CBCT) reduces radiation dose but produces streaking artifacts when reconstructed with conventional algorithms. Deep learning sinogram infilling can address this, but evaluation typically...

Accurate quantitative assessment in positron emission tomography (PET) is essential for reliable lesion characterization and therapy response evaluation. Quantitative accuracy is conventionally investigated using physical phantom...

To develop a machine learning–based method for rapid estimation of patient-specific organ doses in fluoroscopically guided procedures.

Cardiotoxicity is a devastating complication of cancer treatment. Notably, the heart is complex and dose to cardiac substructures (CS) have been strongly linked to radiation-induced cardiac morbidity. The physicist-led, NIH-funde...

Proton therapy is an increasingly adopted cancer treatment due to its high dose conformity enabled by the Bragg peak (BP), reducing radiation exposure to surrounding healthy tissue. However, this steep dose gradient makes treatme...

To evaluate the scalability and impact of the Global Alliance for Medical Physics Education and Research (GAMPER), an open-access hybrid platform addressing critical medical physics workforce shortages in low- and middle-income c...

To develop robust CMOS camera calibration methodology for non-destructive quantification of radionuclides during high-throughput radiotracer synthesis. Estimation of radioactivity is achieved through the detection of Cerenkov lig...

Ionizing radiation acoustic imaging (iRAI) is a noninvasive technique for monitoring radiation delivery. Although iRAI acquisition during irradiation has been demonstrated, its use to quantify spatial dose variations alongside bi...

Cone-beam CT (CBCT) guided bronchoscopy enables precise navigation and sampling of suspicious pulmonary nodules but can be associated with a steep learning curve that limits definitive diagnosis. Existing commercial phantoms are...

We previously developed a system capable of acquiring accurate transrectal 3D micro-ultrasound (mUS) images to allow for visualization and focal treatment of intra-prostatic lesions during prostate brachytherapy. This system made...

To identify and characterize how blood flow, activity concentration, geometry, and scatter affect the counting abilities of a prototype device to quantitatively measure PET radiotracer blood input function at the wrist.

Inequitable access to advanced radiotherapy technologies creates gaps in residency education and limits training experiences. The AAPM Penn–Ohio–West Virginia (POWV) Chapter developed a structured Inter-Residency Exchange Program...

Diagnostic and Interventional Radiology Physics

Accurate radiotherapy delivery requires precise knowledge of soft-tissue anatomy at the time of treatment, particularly for abdominal targets affected by respiration, peristalsis, and inter-fractional anatomical changes. Current...

Radiation induced xerostomia is a common adverse sequela among head and neck cancer (HNC) patients with ~45,000 new cases treated with radiation in the US annually. Current guidelines focus on sparing the mean dose to the parotid...

The ACR Fluoroscopy Dose Index Registry (DIR-FL) collected dose indices for diagnostic fluoroscopy procedures as part of a pilot program to expand the registry beyond interventional procedures. The data serve as the first insight...
