July 2, 2008 - TomoTherapy Inc. closed its Treatment Quality Challenge, originally offering $250,000 to any U.S. cancer center that could surpass the quality of a helical TomoTherapy treatment plan using a single-rotation Varian RapidArc plan delivered in two minutes or less, ending the three-month program without a single entry.
The system was built on a CT scanner platform, thereby integrating true CT Imaging with continuous, 360-degree delivery of targeted radiation.
Adaptive radiation therapy (ART) involves changing a treatment plan between treatment sessions based on quantitative feedback gathered from efficient daily CT Imaging, Hypofractionation involves the delivery of higher doses of radiation in fewer fractions than are used in conventional radiation therapy. The TomoTherapy Hi·Art treatment system was developed to facilitate these kinds of advanced radiation therapy practices, and to facilitate workflow efficiencies with no compromise in treatment quality.
