SHERIDAN, WYOMING – May 5, 2025 – Siemens Healthineers has introduced its Magnetom Flow RT Pro Edition at the European Society for Radiotherapy and Oncology (ESTRO) 2025, marking a significant innovation in magnetic resonance imaging (MRI) tailored for radiation therapy. Designed for operational flexibility and clinical precision, the 1.5 Tesla system addresses longstanding challenges in integrating MRI within radiation oncology environments while offering sustainability and workflow advantages.
Revolutionizing MRI Accessibility in Radiotherapy Settings
Historically, integrating MRI into radiation therapy departments has been hindered by the complex infrastructure requirements of traditional systems, particularly the need for quench pipes and extensive helium cooling. The Magnetom Flow RT Pro Edition removes these barriers with a helium-independent design requiring just 0.7 liters of liquid helium, thanks to its DryCool technology. This eliminates the need for a quench pipe and enables installation directly adjacent to linear accelerators (linacs), facilitating faster transitions between imaging and treatment.
With a compact footprint of only 25m², the system can be seamlessly integrated into existing radiation therapy facilities, minimizing construction demands and associated costs. This enhanced proximity not only supports streamlined operations but also allows patients to undergo MRI scans in treatment position, thereby increasing precision and efficiency.
Operational Efficiency and Sustainability Through Smart Technology
Magnetom Flow RT Pro Edition introduces key features engineered for energy savings and workflow optimization:
- Deep Resolve AI-powered image reconstruction for high-resolution images with reduced scan times.
- Smart System Timer and Eco Power Mode, delivering up to 45% energy savings compared to conventional MRI systems.
- MR-based Synthetic CT, eliminating the need for dual imaging and reducing patient scheduling complexities.
These capabilities make the new scanner a cornerstone for adaptive radiotherapy, where real-time image data enhances personalized treatment strategies while preserving surrounding healthy tissue.
Enhancing Clinical Outcomes with Advanced Imaging
MRI’s superior soft-tissue contrast and functional insights into tumor biology offer clinicians a powerful tool to accurately delineate tumors and organs at risk—key for precision-guided therapy. “We can provide access to the machine at short notice to maintain short intervals between MRI and radiation therapy,” said Dr. Florian Putz, Senior Physician at the Department of Radiation Oncology, Uniklinikum Erlangen, Germany. “In my opinion, MRI plays a key role in radiation therapy for almost all parts of the body. This is particularly true in areas where CT imaging reaches its limits – such as the brain with brain tumors, the head and neck, and the pelvis with pelvic tumors.”
By enabling clinicians to monitor treatment response and adapt plans accordingly, Siemens Healthineers is helping advance the standard of care in radiation oncology.
Strategic Expansion of Imaging Portfolio for Cancer Therapy
Gabriel Haras, Head of Cancer Therapy Imaging at Siemens Healthineers, emphasized the strategic intent behind the launch: “Imaging is the foundation of radiation therapy. While CT remains the basis for treatment planning, the clinical value that MRI adds has a positive impact on patient outcomes. We are very proud to be expanding our portfolio with this dedicated 1.5T MR-Scanner, which is tailor-made to the needs of radiation therapy, easy to use and efficient, powered by AI.”
This development aligns with broader industry movements toward sustainability, AI integration, and patient-centric care in oncology. By addressing both clinical and operational pain points, Siemens Healthineers reinforces its leadership in imaging innovation and its commitment to improving outcomes across cancer treatment pathways.
