Siemens Healthineers unveils ultrafast Accela radiotherapy system
Launched at ASTRO 2026, the high-speed Accela platform can deliver stereotactic treatments in a single breath-hold The post Siemens Healthineers unveils ultrafast Accela radiotherapy system appeared first on Physics World .
At the ASTRO 2026 meeting in Boston, Siemens Healthineers showcased its latest radiotherapy system, Accela. This ultrafast system utilizes NeoArc dynamic modulated arc therapy (DMAT), a delivery technique that rotates the treatment beam continuously around the patient while controlling its shape and intensity for precise dose delivery.
Conventional arc-based methods primarily focus on optimizing treatment plans for dose distribution, but DMAT balances dosimetric objectives and delivery efficiency to optimize speed and precision, ultimately reducing patient time on the treatment table. Siemens Healthineers' Sasa Mutic reported a positive reception from customers and the medical community after Accela's ASTRO unveiling.
Accela's high-speed gantry rotation, dose rates, and dual-layer multileaf collimator allow it to deliver single breath-hold stereotactic treatments, multi-site stereotactic body radiotherapy (SBRT) in under 60 seconds, and large-area treatments with a HyperSight cone-beam CT panel. These ultrafast treatments reduce blood irradiation and preserve lymphocytes, which aid healing, infection-fighting, and cancer-fighting.
The first patient treatments with Accela are set for December in Europe, with CE marking and FDA clearance expected early the following year. Maastro in the Netherlands is among the first centers to use Accela, initially treating small lung tumors, lung metastases, brain tumors, and vertebrae metastases – sites requiring high-precision radiation while sparing healthy tissue and nearby organs.
