The Catalyst HD™ system, especially designed for use in proton therapy and for advanced stereotactic treatments, has been released. The installations of the first two systems in Europe are ongoing.

Catalyst HD™ is based on the patented C-RAD technology. With a unique arrangement of multiple 3D cameras and newly developed software, the system is convincing with superior performance for all treatments where couch rotations are applied.

All interfaces for respiratory gating and for treatment couch control, will be compatible and used with the Catalyst HD™. Existing software modules for Patient Setup and Positioning, Motion Monitoring during treatment and Respiratory Gating are adopted to the new system.

Stereotactic radiosurgery is a form of radiation therapy where the focused x-ray beam is delivered with very high accuracy into a small volume within the body. Therewith tumor tissue can be treated efficiently with minimizing the dose delivered to healthy tissue around the tumor. This treatment technique is especially used for head and neck treatments.

Tim Thurn, CEO of C-RAD AB:

“With the presentation of Catalyst HD C-RAD answers the high demands of advanced clinicians and underlines its role as market leader in the field of surface tracking. The interest for the new Catalyst HD has been overwhelming. A number of quotations are pending both in Europe and in the US.”
