Philips Debuts CT and MR Innovations in Radiation Therapy

Philips introduced the radiation oncology solutions Rembra RT and Areta RT CT platforms, as well as the latest helium-free BlueSeal RT 1.5T MR system, at this year’s American Society for Radiation Oncology (ASTRO) meeting.

The Rembra RT and Areta RT scanners product clearer, more consistent images to see tumors in more detail and plan treatments with confidence. Their image reconstruction speeds are up to 106 images per second, with touchscreen gantry controls. A wide 85-cm extended field of view and next-gen 4DCT imaging capabilities can capture a full respiratory cycle in one scan up to 500 scan seconds with breath rates of 4-40 breaths per minute.

“Philips invented CT Simulation and introduced the industry’s first Big Bore RT system,” said Dan Xu, Business Leader of CT at Philips. “With Rembra RT and Areta RT, we’re once again setting new standards in radiation therapy, empowering care teams with the precision, dependability, and speed they need to deliver the best outcomes for patients.”

The company is also working with MVision AI to explore including its Contour+ AI-powered auto-segmentation software with Philips CT simulators, including the new Rembra RT and Areta RT systems. Contour+ offers automatic delineation of organs at risk and lymph node areas.

Philips is also debuting BlueSeal MR RT in North America, its latest helium-free 1.5T 70 cm MR system for radiation oncology. BlueSeal RT is powered by AI-based SmartSpeed Precise acceleration software for enhanced simulation confidence.

BlueSeal RT reduces registration errors to help protect healthy organs. It provides full MR-only simulation protocols in as little as ten minutes.

The technology makes it possible to install MR systems in complex clinical environments like radiation oncology departments. Its lightweight, vent-pipe-free design opens new siting possibilities like basements, bunkers, or higher floors.

“BlueSeal RT is leading the way in MR for radiotherapy,” said Ioannis Panagiotelis, Ph.D., business leader MR at Philips. “By combining helium-free sustainability with AI-powered acceleration, we’re enabling radiation oncology teams to plan and simulate with greater speed, accuracy, and confidence—while enhancing the patient experience.”

Earlier this month, the company expanded its multi-year partnership with Masimo to accelerate development and delivery of next-generation patient monitoring solutions.
