Elekta X-ray Volume Imaging (XVI)
September 13, 2013 – Integrated with Versa HD linear accelerator, Elekta has introduced new intra-fraction imaging capabilities within its X-ray Volume Imaging (XVI) system. During treatment, XVI now provides the tools to monitor and manage internal motion, supporting the clinician's efforts to increase therapeutic doses delivered to the tumor while reducing healthy tissue exposure.
"Regardless of patient immobilization, both the tumor and adjacent critical structures may move during treatment delivery. Historically, this has presented a significant challenge in delivering highly targeted treatments," says Dee Mathieson, Senior Vice President, Oncology Business Line Management.
"On a second by second basis, the precise location of the tumor and sensitive healthy structures can now be visualized, helping clinicians accurately deliver dose to the tumor while minimizing normal tissue exposure,” she adds
Elekta's XVI, which is also available on other Elekta radiotherapy delivery systems, includes 2-D, 3-D and 4-D intra-fraction imaging to support live imaging during sophisticated delivery techniques, such as Volumetric Modulated Arc Therapy (VMAT).
The new capabilities within XVI include seamless integration with Elekta's Mosaiq image-enabled oncology information system. XVI and Mosaiq work in harmony to deliver highly automated imaging workflow for improved control, efficiency, and performance. With image data available within the Oncology Information System, patient images, as well as setup and correction data, can be accessed as an integral part of the patient's electronic medical record.
The XVI 5.0 is pending FDA 510(k) clearance and not yet available for sale in the United States.
