TomoTherapy, Vision RT team for 3D imaging technologies
TomoTherapy has partnered with Vision RT to expand imaging options for Hi-Art treatment system users. The companies are jointly introducing AlignRT 3D imaging technology for the Hi-Art platform at the annual meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Boston, Sept. 21-25.

TomoTherapy will distribute AlignRT for use with both its TomoHelical and new TomoDirect delivery modes, according to the Madison, Wis.-based TomoTherapy and the London-based Vision RT.

The companies said that AlignRT for the Hi-Art platform will consist of two ceiling-mounted 3D camera units, each focused toward the external isocenter of the radiotherapy device. 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 software will be used to register real-time image data to the reference surface scan, and—within seconds—provide new couch coordinates for patient positioning.
