Accuray and Siemens agree to integrate diagnostic CT imaging and robotic radiosurgery solutions

Accuray : 11 April, 2007  (New Product)
Accuray has signed a co-marketing and distribution agreement with Siemens Medical Solutions USA that enables Accuray to integrate its CyberKnife Robotic Radiosurgery System and RoboCouch Patient Positioning System with a Siemens SOMATOM computed tomography (CT) scanner with a sliding gantry configuration.
The combination of these technologies in the treatment room further enhances visibility of internal structures at the time of treatment.

Unlike other in-room imaging solutions, the Siemens SOMATOM 3D and 4D system is designed to ensure clinicians have access to the highest diagnostic quality images and 4D image data during patient setup. Other radiation therapy systems have begun to offer slower, lower quality imaging techniques such as cone beam imaging to verify patient position. In contrast, the CyberKnife System with Siemens CT sliding gantry solution enables faster, higher resolution imaging setup. This, combined with the CyberKnife System’s ability to continually track, detect and correct for tumour and patient movement, enables the CyberKnife System to deliver enhanced treatment quality and throughput.

The clinical benefits of the in-room diagnostic CT system are realised mainly in the treatment of tumours that move with respiration, such as lung, liver and pancreas, as well as prostate tumours, which are impacted by bowel and bladder function. Unlike cone beam CT, diagnostic CT provides higher resolution imaging and allows for differentiation of soft tissue structures.

In the treatment of prostate tumours, this enhanced ability allows for visualisation of physiological changes like rectal or bladder filling, to ensure the organs haven’t moved into the treatment field since the preliminary planning CT. Additionally, for tumours that move with respiration, the addition of in-room 4D CT helps to account for tumour motion and deformation between the planning CT and the CT on the day of treatment.

'This agreement with Siemens further validates Accuray’s commitment to providing innovative solutions that meet clinicians’ needs,” said Euan S Thomson, PhD, president and chief executive officer of Accuray. 'By combining the best systems in in-room imaging and robotic radiosurgery, we are able to offer clinicians a more efficient means for positioning patients and ensuring extreme accuracy in targeting their tumours.”
