University of Wisconsin-Madison selects RayStation

The Department of Human Oncology at the University of Wisconsin-Madison has chosen RayStation® as its next radiation therapy treatment planning system. The agreement was signed in late December 2016, and the purchase is planned to occur in two phases.

RayStation will be used for external beam treatment planning at the University of Wisconsin and satellite clinics. The agreement also covers affiliates and other partnerships.  The purchase includes advanced features such as deformable registration, dose accumulation and adaptive radiation therapy planning. The university will also be an early investigator of TomoTherapy™ planning* in RayStation, which allows for single-platform planning including the Accuray TomoTherapy machines.

John Bayouth, Chief of Radiation Oncology Physics at the Department of Human Oncology, says: “The university is constantly developing and extending its capabilities in the realm of radiation therapy treatment planning.  Our intention is to explore plans that leverage the diversity of treatment delivery technologies in our system and determine the optimal approach for each patient.”

Johan Löf, CEO of RaySearch Laboratories, says: “The University of Wisconsin-Madison is well known for its capabilities and long track record in radiation treatment of cancer. The university has conducted pioneering research since the advent of three-dimensional patient imaging and has also spawned several successful companies within treatment planning and delivery. We share a spirit of innovation, and our relationship will lead to further advancement of cancer care. This order, and over 40 more RayStation orders that we received during the fourth quarter, contributed to a very strong finish for 2016.”
