To quantify the impact of daily MR-guided adaptive replanning for prostate SBRT on protocol dose-constraint fulfillment, compared with non-adapted reference SBRT plans recalculated on daily anatomy, using both constraint-level pass/fail classification and the...

To evaluate the longitudinal dosimetric and mechanical performance of the Elekta Harmony LINAC over its first year of clinical use in our center.

To develop and implement an automated quality assurance application for radiation therapy treatment plan verification following AAPM TG-275 guidelines, enabling comprehensive comparison between Elekta Monaco treatment planning system (TPS) and MOSAIQ oncology...

Daily anatomical changes can invalidate the geometric, dosimetric, and biological assumptions of reference treatment plans. Quantitative evidence describing fraction-level deviations across disease sites remains limited, and adaptive workflows are often drive...

Low muscle quantity, defined by computed tomography (CT)-based skeletal muscle index (SMI), is emerging as a predictor of clinical outcomes in patients with HNC. This study aims to evaluate whether CT-defined SMI is associated with all-cause mortality in pati...

Dose prediction models operate in the CT dose domain and require a conventional optimization step to translate the predicted dose into deliverable parameters in beam’s-eye view (BEV). To address the taxing direct aperture optimization (DAO) process, directly...
