MEVION DELIVERS WISCONSIN'S FIRST COMPACT PROTON THERAPY SYSTEM TO THE FROEDTERT & THE MEDICAL COLLEGE OF WISCONSIN CLINICAL CANCER CENTER

Mevion Medical Systems, a leading provider of proton therapy solutions, today announced the successful delivery of its MEVION S250i Proton Therapy System^® to the Froedtert & the Medical College of Wisconsin Clinical Cancer Center at Froedtert Hospital campus. This milestone marks a significant advancement in cancer care for adult and pediatric patients in Wisconsin, providing access to a highly targeted and effective treatment option.

First Compact Proton Therapy System in Wisconsin

Unlike traditional radiation therapy, proton therapy uses a unique characteristic of protons—their ability to deposit most of their energy at a specific depth—to target tumors with exceptional accuracy. The MEVION S250i is the first compact proton therapy system to be installed in Wisconsin, making the Froedtert & MCW Cancer Network a leader in providing this innovative technology to patients in the region.

Unique Elevated Treatment Room Installation

In another first, the MEVION S250i is installed in an elevated treatment room in a specially designed clinic. Its intentional design places it on the same level as the existing radiation oncology clinical space on the third floor of the cancer center. This innovative approach will streamline patient flow and enhance operational efficiency. The MEVION S250i is the most compact proton therapy system in the world, with all necessary equipment housed within a single room. This compact design allows for greater flexibility in installation, making proton therapy accessible to more hospitals and clinics.

Advanced Technology for Improved Patient Outcomes

The MEVION S250i is a compact and versatile proton therapy system designed to deliver precise radiation treatment to tumors while minimizing damage to healthy tissues. With its advanced technology and streamlined workflow, the system offers a range of benefits for patients, including reduced treatment time and improved quality of life.

"We are thrilled to partner with the Froedtert & the Medical College of Wisconsin Cancer Network to bring this cutting-edge technology to the region," said Tina Yu, PhD, CEO and President at Mevion Medical Systems. "The MEVION S250i will provide patients with access to the most advanced cancer care available, and we look forward to seeing the positive impact it will have on the community."

"Proton therapy represents a significant advancement in cancer care, offering patients a highly precise and targeted treatment option," said Christopher Schultz, MD, FACR, radiation oncologist with the Froedtert & the Medical College of Wisconsin Cancer Network; professor and chairman of the Department of Radiation Oncology with the Medical College of Wisconsin. "By delivering radiation directly to the tumor while minimizing damage to surrounding healthy tissue, we can improve outcomes, reduce side effects and enhance the overall quality of life for our patients."
