Stanford Health Care Installs First-Ever MEVION S250-FIT Compact Proton Therapy System

Mevion Medical Systems announces the installation of the MEVION S250-FIT Proton Therapy System™ at Stanford Health Care, a milestone for proton therapy technology. This installation in a conventional linear accelerator (LINAC) vault integrates advanced patient treatment capabilities within existing infrastructure.

Manufactured in Littleton, Massachusetts, and transported via standard highway from Boston to Palo Alto, the MEVION S250-FIT is the only domestically built compact proton accelerator. Its integration with the MARIE™ upright patient positioning system from Leo Cancer Care and a diagnostic CT scanner offers improvements in patient comfort and treatment precision.

The system utilizes RayStation from RaySearch Laboratories, a leading proton therapy treatment planning software, enhancing precision and efficiency in patient care.

Sridhar Seshadri, Stanford Health Care’s SVP and President of the Cancer Center, emphasizes the project’s alignment with their commitment to advancing cancer treatment, “Integrating this advanced technology enables us to offer more precise and effective treatments to our patients.”

Tina Yu, Ph.D., CEO of Mevion Medical Systems, comments on the collaboration: “Partnering with an innovation leader like Stanford is key to advancing compact proton therapy solutions, making them accessible within established oncology workflows.”

This installation at Stanford, recognized for its pioneering role in radiation therapy and as a National Cancer Institute-designated Comprehensive Cancer Center, signifies a major step in expanding the accessibility of advanced cancer treatments.
