Enhanced Patient Positioning System Aids Image Guided Radiation Therapy

Brainlab releases an advanced version of the ExacTrac Patient Positioning system for IGRT after more than 1 million frameless treatments

July 27, 2012 — Today, Brainlab officially unveils the new ExacTrac 6.0 patient positioning system, delivering key improvements for both frameless radiosurgery and radiotherapy treatments. This new system aims to further increase clinical value, deliver intuitive workflows and enable refined integration with peripheral systems. For more than two decades, Brainlab has been refining and revolutionizing precise patient setup for stereotactic treatments. Now, over 500 institutions have demonstrated their trust in the ExacTrac IGRT system with more than one million treatments performed.

ExacTrac uses high-resolution stereoscopic X-ray images to instantly detect and visualize internal structures and their location inside the body before and during treatment. A selective, intelligent image fusion algorithm allows the elimination of artifacts and ambiguities caused by objects not rigidly correlated to the target structure. Clinicians can then correct patient position in six dimensions of freedom in order to accurately target the treatment area.

Three major American facilities have already acquired the new system, including Memorial Sloan Kettering Cancer Center in New York City, UCSF Medical Center in San Francisco, and MD Anderson Cancer Center in Texas, which acquired two new systems and upgraded their existing installation.

ExacTrac 6.0 features new technology and workflow management:

  • New dual generator allows for simultaneous imaging, significantly reducing the setup time and further enhancing the utilization of intra-fraction snap verification
  • Remote control of the robotics module eliminates the need to enter the treatment room for rotational corrections
  • Cone beam CT integration allows for patient alignment in 6-D based on volumetric cone beam images
  • Advanced integration with Record and Verify system enables users to export shifts and images in DICOM RT format and review offline

The new ExacTrac 6.0 platform will be showcased at this year's American Association of Physicists in Medicine (AAPM) annual meeting in Charlotte, N.C.
