Manual plan checking is time-consuming and prone to variability across reviewers. To improve consistency and reliability in the plan-check workflow, we developed a fully automated RayStation plan-check system that performs more than 30 checks across eight key...

Linear accelerator (LINAC) coordinate system conventions have historically evolved heterogeneously, with vendors and institutions adopting mixed non-IEC standards. While clinically functional, this lack of uniformity introduces added complexity and potential...

Proton radiation therapy (PRT) is an effective modality for ocular cancers. Substantial evidence indicates that proton relative biological effectiveness (RBE) increases with linear energy transfer (LET). In vitro DNA double-strand break (DSB) and cell surviva...

Surface Guided Radiation Therapy (SGRT) systems are increasingly used for patient positioning and motion management in radiotherapy. However, their performance may be influenced by variations in patient skin tone, as differences in optical absorption and refl...

VMAT total body irradiation (TBI) planning is complex and time-intensive, involving multiple isocenters, junction management, and iterative hotspot control. Many automation approaches still require repeated user interaction, limiting efficiency gains. This wo...

Ultra-high Dose-Rate (UHDR) radiotherapy challenges conventional dosimetry methods. Optical calorimetry (OC) enables direct, dose-rate-independent measurement of spatially and temporally resolved dose-to-water distributions. This work validates OC as a dosime...

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 gamma criteria.
