About Us

LinearPhysics is the result of many years of clinical experience, including treatment planning, machine modeling, developing quality assurance protocols, data collection, and testing. Over the last 15 years we have commissioned more than 100 linear accelerators, including all Varian, Siemens, and Elekta models. In the collection of data, we have utilized IBA, Sun Nuclear, and PTW scanning systems. We have measured data for Eclipse, Monaco, RayStation, and Pinnacle treatment planning systems.

We strive to serve every client with precision, flexibility, and excellent communication.
