The spread-out Bragg peak (SOBP) technique uses ridge filters to broaden the depth-dose profile, producing a dose distribution similar to a single-field-uniform(SFU) approach. In contrast, the single-energy pristine Bragg peak(SEPBP) approach relies on range...

Shortages of trained medical physicists persist across Africa. Needs-assessment surveys were utilized to determine trainee interest and medical physics curricular gaps to aid in design of hands-on outreach workshops for the African School of Physics, a severa...

Fluoroscopy education and clinical literature dealing with videofluoroscopic swallowing studies commonly emphasize frame rate as the primary determinant of temporal resolution and diagnostic accuracy. However, frame integration or frame averaging, a fundament...

Treatment plan review is normally focused on ensuring the quality of individual plans. However, what begins as a routine treatment plan review can occasionally result in hard-earned lessons that lead to significant improvements in clinical practice -- lessons...

We report the first clinical implementation integrating a 6D upright treatment chair and a vertical CT system for image-guided proton therapy on a synchrotron-based fixed-beamline. This design aims to improve patient workflow and reduce the facility footprint...

Grayscale ultrasound is widely used in breast screening, diagnosis, and ultrasound-guided biopsy, particularly for detecting breast lesions. However, current Quality Control (QC) methods provide limited and often subjective assessment of lesion detectability...

Proton density fat fraction (PDFF) is widely used as a quantitative MRI biomarker in clinical care. Accurate PDFF measurement requires robust quality control, commonly performed using phantom-based assessment. This work evaluates an automated algorithm for qu...

On-board kV imaging systems on proton therapy machines predominantly rely on scintillator-based energy-integrating detectors (EIDs) for planar imaging and cone-beam CT (CBCT). However, EID-based CBCT is limited by suboptimal image quality and insufficient qua...

In digital radiography (DR), the Exposure Index (EI) and Deviation Index (DI) provide standardized feedback on whether image receptor exposure is appropriately matched to patient size and clinical task. However, systematic, context-aware analysis of EI and DI...
