BOSTON — Siemens Healthineers introduced a new radiation therapy system called Accela Sept. 27 at the American Society for Radiation Oncology (ASTRO) annual meeting.
The system is built around a new dynamic modulated arc therapy (DMAT) technique called NeoArc, which allows stereotactic treatment to be delivered in a single breath, and multi-site stereotactic body radiotherapy (SBRT) can be performed in as little as 60 seconds, according to the company. Accela’s planning software uses AI and optimization algorithms that allow clinicians to evaluate plan quality versus delivery speed, Siemens said.
The linear accelerator of the system has the following characteristics:
- A large HyperSight cone beam CT imaging panel
- A newly designed multi-leaf collimator
- Gantry rotation of 2.5 revolutions per minute
- Dose rates up to 40 Gy/min
- A new 8 MV filterless flattening energy setting
“It is based on a fundamentally modern architecture and introduces a generational shift in treatment planning,” said Dee Khuntia, MD, chief medical officer at Varian, the cancer care business of Siemens.
The company developed Accela and NeoArc with input from a cancer center advisory group that provided clinical input, research collaboration and product evaluation. The group includes Mayo Clinic; Washington University School of Medicine in St. Louis; University Hospital Zurich; Seidman Cancer Center at University Hospitals Cleveland Medical Center; Maastro – Maastricht Institute of Radiation Oncology; Brigham Comprehensive Cancer Institute; and Memorial Sloan Kettering Cancer Center.
Accela is awaiting approval from the U.S. Food and Drug Administration.
