August 15, 2019 — Mevion Medical Systems and C-RAD announced the integration between the C-RAD Catalyst PT and the Mevion S250i proton therapy system. The union of both products supports a seamless workflow with uninterrupted patient surface tracking and monitoring from setup through treatment.
C-RAD offers a specific version of its Catalyst System for use in proton and particle therapy - the Catalyst PT, based on the Catalyst technology and software.
Maastro Proton Therapy (Maastricht, The Netherlands), equipped with the Mevion 250i Proton Therapy System, and C-RAD announced a strategic agreement in 2018 to install the Catalyst PT at the center. C-RAD and Mevion co-developed a solution based on both companies’ products that allows a high level of integration to enhance user comfort and patient safety.
Guided by the expertise and requirements of Maastro Proton Therapy, the two industry partners focused on developing the interface required to support a seamless workflow, including automatic patient position correction and monitoring throughout the entire treatment process.
The installation of the Catalyst PT at Maastro Proton Therapy was commissioned over the past month and has been released for clinical operation beginning this August. The center will be deploying the Catalyst PT especially for thoracic tumor indications treated on the Mevion system.
Geert Bosmans, managing director of Maastro Proton Therapy said, “To provide our patients with an improved high-quality treatment plan we installed the C-RAD surface tracking system in our center. We will use it to accurately position and continuously monitor our patients during treatment for increased high-precision radiation therapy.”
The Catalyst PT system is now available to current and future Mevion customers.
