SAN ANTONIO - Radiation oncology firm Varian Medical Systems is launching ProBeam 360°, a new single-room proton therapy system, at this week's American Society for Radiation Oncology (ASTRO) meeting in San Antonio.
ProBeam 360° features a 360° rotating gantry designed to enable efficient intensity-modulated proton therapy (IMPT) as well as high-quality conebeam CT (CBCT) from any angle. The configuration reduces the need for patient repositioning and reimaging, according to the company, and Varian's RapidScan technology is also available for motion management by delivering each field in a single patient breath-hold.
ProBeam 360° is designed to be sited in smaller spaces, with a footprint that's 30% smaller than the footprint of Varian's previous proton therapy system; this helps reduce vault construction costs by 25%. Other features on ProBeam 360° include Varian's high-definition pencil-beam scanning technology, which can be combined with iterative CBCT to enable ProBeam 360° to deliver adaptive precision radiation therapy during treatment, improving the precision of proton therapy.
In other Varian ASTRO news, the company revealed that it is working on a multimodality adaptive radiotherapy treatment suite that is based on artificial intelligence (AI) and is being designed to improve clinician workflow and make it easier for radiation therapy sites to offer adaptive radiation therapy.
The suite will incorporate treatment planning, treatment delivery, and patient monitoring, and it will support MRI, CT, and PET, all available at the radiotherapy console. Varian shared details of the project at its users' meeting at ASTRO 2018.
