Philips Showcases Next-Generation CT and MR Innovations in Radiation Therapy at ASTRO 2025

At the American Society for Radiation Oncology (ASTRO) 2025 Annual Meeting,  Philips is unveiling major advancements in radiation oncology. These include two new CT platforms – Philips Rembra RT and Philips Areta RT – as well as the latest helium-free BlueSeal RT 1.5T MR system. Together, these innovations aim to deliver greater precision, efficiency, and sustainability in cancer care.

CT imaging remains the cornerstone of radiation therapy planning, but oncology teams face increasing pressure to deliver faster, more accurate, and more consistent results. Philips’ new Rembra RT and Areta RT scanners address these needs with:

• Sharper imaging for better tumor visibility and treatment confidence.
• Ultra-fast reconstruction speeds of up to 106 images per second.
• User-friendly controls, with touchscreen gantries that help 91% of care teams work more efficiently.
• Expanded capabilities, including 85 cm extended fields of view and next-generation 4DCT for full respiratory cycle imaging.

The systems also enable remote collaboration for planning and training, helping teams stay connected without additional staffing. With Philips’ Tube for Life Guarantee and a 20-year service life, hospitals gain lasting value and reliability while reducing costs. Patients benefit from faster workflows, reduced wait times, and improved comfort through high-performance positioning tables and shared-use radiology capabilities.

“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,” said Dan Xu, Business Leader of CT at Philips.

Philips is also exploring collaboration with MVision AI, aiming to integrate its Contour+ auto-segmentation software for rapid delineation of organs and lymph nodes.

Alongside its CT breakthroughs, Philips is introducing the BlueSeal RT, a helium-free 1.5T MR system tailored for radiation oncology. Powered by AI-based SmartSpeed Precise software, it enhances tumor visualization while reducing registration errors, improving confidence in therapy planning.

Key benefits include:

• MR-only imaging with protocols in as little as 10 minutes, improving patient comfort.
• Sustainable design, with helium-free operation and PowerSave+ efficiency to lower energy use.
• Flexible siting options, thanks to a lighter, vent-pipe-free system design suited for basements, bunkers, or upper floors.

“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,” said Ioannis Panagiotelis, PhD, Business Leader MR at Philips.
