Siemens Incorporates Prowess Software into Linear Accelerators

February 20, 2008 - Siemens Healthcare announces an exclusive partnership with Prowess Inc. to develop advanced radiation oncology treatment planning software for integration into Siemens' linear accelerators.

This agreement authorizes Siemens Healthcare to share the basic intellectual property of Prowess' patented Direct Aperture Optimization (DAO) planning software, allowing Siemens to incorporate Prowess’ software into the treatment planning tools for its linear accelerators, which, according to Siemens, will help users to reduce the number of segments, monitor units and treatment times.

The Prowess DAO-based Plan-to-Patient tool for Adaptive Radiation Therapy (ART) has been clinically evaluated and is planned to be available in the spring of 2008. The tool works with Siemens' CTVision System, a SOMATOM CT Sliding Gantry on rails combined with an ARTISTE or ONCOR Linear Accelerator. DAO reportedly enables users to make on-line plan corrections based on actual pre-treatment CT scans taken in the treatment room, while the patient is on the linear accelerator’s treatment table.

Siemens is also working on the development of a single arc radiation treatment called Cone Beam Therapy (CBT). The combination of CBT with DAO-based planning software will help improve tumor control for many disease sites, while sparing as much healthy tissue as possible, according to Siemens.
