In this short video, filmed at ASTRO 2022, LAP’s Drew Bullock introduces the company’s RadCalc software system for patient quality assurance (QA), including 3D Collapsed Cone and Monte Carlo algorithms for plan validation and the 3D EPID module for both pre-treatment phantom-free QA workflows as well as in vivo delivered dose QA for the patient. We also hear from LAP’s Jennifer Beckford, who presents the Thales 3D MR scanner, an MR-compatible motorized water phantom for commissioning and QA of bore-type linacs, including both the MRIdian and Halcyon treatment systems.
