May 4, 2017 — Mevion Medical Systems announced a strategic agreement with medPhoton GmbH to integrate ImagingRing, an innovative cone beam computed tomography (CBCT) system for volumetric image guidance, with the Mevion S250i with Hyperscan, Mevion’s pencil-beam scanning proton therapy system. The new CBCT offering will debut at the 36th annual meeting of the European Society for Radiotherapy & Oncology (ESTRO), May 5-9 in Vienna, Austria.
By adding fully integrated cone beam imaging to Mevion’s suite of in-room image guidance capabilities, Mevion and medPhoton provide simplicity of workflow and more precise and efficient treatment delivery.
CBCT imaging is an important capability in the treatment room to precisely position patients for pencil beam proton therapy. In-room CBCT, when integrated to Mevion’s Verity image-guided patient positioning system, will enable users to treat patients with the latest image-guided radiation therapy (IGRT) technology and deliver high-precision positioning and adaptive proton therapy in a simple workflow. Clinicians will be able to track anatomical changes throughout the course of treatment and adapt the treatment plan as needed to ensure accurate proton dose delivery.
ImagingRing will be fully integrated into optimized workflows with the Mevion S250 Series and Verity Patient Positioning System. Together with Mevion’s 6D robotic treatment couch, it enables detailed imaging of the tumor and organs at risk with the patient positioned at the treatment isocenter.
The Mevion S250i proton therapy system is not yet U.S. Food and Drug Administration (FDA)-cleared.
