Treating tumours

Accuray Incorporated and Siemens Medical Solutions have signed an agreement to collaborate in the development of advanced imaging and software solutions targeted for use in radiosurgery and radiotherapy.

The two companies will jointly focus on the integration and optimization of Siemens computed tomography (CT) imaging technology with Accuray's CyberKnife Robotic Radiosurgery System. They will also work towards the integration of Accuray's advanced targeting techniques into Siemens radiotherapy product line.

Accuray develops and markets the CyberKnife Robotic Radiosurgery System, the world's first radiosurgery system that utilises intelligent robotics to treat tumours anywhere in the body with sub-millimetre accuracy.

The CyberKnife System treats patients in single or staged (typically up to five) sessions by delivering multiple beams of precisely directed radiation that converge upon the tumour while minimizing injury to surrounding healthy tissue. Image guidance and computer controlled robotics combine to continuously track, detect and correct for tumour and patient movement throughout the treatment. Because of this precision and accuracy, no head or body frame is required.
