AlignRT for the HiArt platform is said to consist of two ceiling-mounted 3D camera units, each focused toward the external isocenter of the radiotherapy device. Immediately prior to treatment, the patient will lie on the treatment couch for initial set-up. The cameras will then acquire a surface scan of the body in treatment position, and the software will be used to register real-time image data to the reference surface scan and provide new couch coordinates for optimal patient positioning.
Corey Lawson, director of product strategy for TomoTherapy, said: “The CTrue imaging technology will continue to be used extensively when the tumor is deep-seated, or can move internally without external evidence. However, we believe AlignRT will prove useful in approximately 40% of cases, based on a standardized mix. Where this technology is best suited, we estimate a 50% reduction in setup and registration time.”
Norman Smith, CEO of Vision RT, said: “We are delighted to partner with TomoTherapy to expand imaging options while boosting patient throughput for this next-generation platform. In addition, through this partnership, we look forward to developing advanced features that will further enhance the accuracy and precision of TomoTherapy treatments for a broad patient population.”
