Radiation therapy depends on more than advanced technology – it depends on precision. In this episode of the Physics World Weekly Podcast, sponsored by One Physics, James Giltz, Director of Commissioning Services at One Physics, discusses the critical role medical physicists play in ensuring li
near accelerators (LINACs) are commissioned accurately and operate safely throughout their lifecycle. From planning new cancer centers to supporting ongoing clinical operations, he explains why commissioning is one of the most important steps in delivering effective radiation therapy.
Listen to the Podcast:
The conversation explores how One Physics has developed a highly specialized commissioning process that combines experienced medical physicists with proprietary technology to deliver fast, consistent, and thoroughly validated results. Giltz shares how the company’s Quadrant software helps analyze hundreds of thousands of data points, identify potential issues in real time, and provide independent verification that gives hospitals and clinicians confidence in their treatment systems.
Beyond commissioning, the discussion covers the growing demand for outsourced medical physics services, including quality assurance, shielding evaluations, and clinical support. Giltz also addresses the nationwide shortage of medical physicists and how organizations like One Physics are helping bridge the gap by expanding residency programs and investing in the next generation of professionals.
