Siemens Healthineers launches Accela radiotherapy system with NeoArc
- Siemens Healthineers launched Accela, radiotherapy system engineered around NeoArc, according to company announcements.
- The Accela radiotherapy solution features a large HyperSight cone-beam CT imaging panel and a newly designed multi-leaf collimator.
- It's faster than previous systems, it's built on a fundamentally modern architecture, and it introduces a generational shift in treatment planning.
Siemens Healthineers launched Accela, radiotherapy system engineered around NeoArc, according to company announcements. The platform combines speed and precision to enable single breath-hold stereotactic treatments and multi-site stereotactic body radiation therapy in as little as 60 seconds, according to company announcements.
Architecture and Technical Specifications of Accela
The Accela radiotherapy solution features a large HyperSight cone-beam CT imaging panel and a newly designed multi-leaf collimator. The system supports high-speed gantry rotation at 2.5 revolutions per minute, dose rates reaching up to 40 Gray per minute, and an eight-megavolt flattening filter-free energy setting. Advanced algorithms and artificial intelligence built into the planning software allow clinicians to balance treatment plan quality with delivery speed. Dee Khuntia, chief medical officer at Varian, the Siemens Healthineers cancer-care business, stated that the system introduces a generational shift in treatment planning.
It’s faster than previous systems, it’s built on a fundamentally modern architecture, and it introduces a generational shift in treatment planning. But what excites me most is its potential to alter the biological response to radiotherapy. That’s not incremental progress; it’s a new chapter.

Clinical Collaboration and Industry Impact
Development of Accela and the NeoArc technique involved years of collaboration with an advisory group of leading cancer-research institutions. Participating centers included the Mayo Clinic, Washington University School of Medicine Siteman Cancer Center, University Hospital Zurich, Seidman Cancer Center at University Hospitals Cleveland Medical Center, Maastro – Maastricht Radiation Oncology Institute, Mass General Brigham Cancer Center, and Memorial Sloan Kettering Cancer Center. Arthur Kaindl, head of Varian, noted that the platform builds on decades of infrastructure, including a global imaging business, an established radiation-oncology installed base, and long-term clinical relationships. Sun Nuclear also announced a validated adaptive quality assurance solution to support the new system.
