Siemens Healthineers has released the Accela radiotherapy system, which is designed to deliver multi-site stereotactic body radiation therapy (SBRT) in 60 seconds. This advancement aims to streamline treatment sessions for patients undergoing targeted cancer care.
Why it matters
By significantly reducing the duration of sessions, this technology may improve patient comfort and efficiency during radiation therapy protocols. It marks a shift toward faster, more precise delivery of high-dose radiation to specific tumor sites.
The Accela system utilizes NeoArc dynamic modulated arc therapy to complete multi-site SBRT in 60 seconds. This figure represents the total delivery time for these treatments, though clinical performance outcomes are currently pending peer-reviewed validation.
The players
Siemens Healthineers
A global medical technology company specializing in imaging, laboratory diagnostics, and advanced cancer treatment solutions.
The details
The Accela radiotherapy solution leverages NeoArc dynamic modulated arc therapy, a technology that allows for continuous radiation delivery while the machine rotates around the patient. This integration enables practitioners to perform single breath-hold stereotactic treatments, which can enhance precision by limiting organ motion. By optimizing the beam delivery path, the system minimizes the time patients must remain immobilized during complex procedures.
Timeline
September 27, 2026: Siemens Healthineers introduced the Accela radiotherapy system in Boston.
Health Landscape
The introduction of the Accela system represents the latest evolution in the long-term trend toward shorter, more intensive radiation therapy schedules. It sits alongside ongoing efforts to optimize stereotactic body radiation therapy (SBRT) delivery protocols for improved patient throughput.
If you are currently undergoing or planning to start radiation therapy, discuss with your oncology team whether your specific treatment plan could benefit from these faster delivery methods. Ask your physician how shorter session times might impact your comfort and overall care plan.
The takeaway
Advancements in radiotherapy are increasingly focused on reducing the time patients spend in the treatment chair during complex sessions. Patients should track their treatment schedules and discuss new, more efficient radiation delivery options with their oncology specialists.
