Open-source software offers a transparent and cost-effective alternative to commercial, patient-specific quality assurance (PSQA) systems; however, clinical validation remains essential. This study aims to validate open-source Pylinac (PL) based gamma analysi...

This study investigates the limitations of Collapsed Cone Convolution (CCC) dose calculation algorithm in accurately modeling dose perturbations in nanoparticle-enhanced radiotherapy for lung tumors. The feasibility of CCC is compared with a Monte Carlo (MC)...

The goal of this project is to standardize and automate the QA program of a multi-location radiation oncology practice. Our practice includes eleven linear accelerators, five CT scanners, and four HDR afterloaders, across four separate treatment centers.

Annual linac beam scanning QA is time-intensive and often relies on manual data handling, spreadsheet analysis, and site-specific workflows. These steps can be tedious and inconsistent, even when the underlying measurements are solid. The goal of this work wa...
