Andover, Mass. - Royal Philips Electronics (NYSE: PHG, AEX: PHI) has announced the release of its Model Based Segmentation (MBS) software for Image Guided Radiation Therapy (IGRT) workflow enhancement. The MBS software, an upgrade on the current Pinnacle3 Radiation Therapy Planning system, was showcased at the American Association of Physicists in Medicine (AAPM) meeting recently in Orlando, Fla.

The current Pinnacle3 system combines AcQSim3 simulation, Syntegra image fusion and P3IMRT modules to provide a powerful oncology toolbox capable of sculpting radiation doses to tumors. The new MBS software offers a revolutionary advancement in reducing the time it takes to contour tumors and anatomical structures and is a crucial step toward the future of IGRT and the ability to quickly adapt patients' treatment plans based on their response to daily treatment.

The MBS software includes an anatomical library of 3D patient organ structure models. Users can simply drag and drop the models onto patient image data and the software automatically adapts to each patient's anatomy. The library of anatomical models grows as new patient data are added, providing a unique ability to build a library based on regional demographic or clinical practice specialties.


"Philips investment in research and clinical IGRT partnerships has paid off with the launch of MBS," said Philips project manager David Robinson, a Certified Medical Dosimetrist. "IGRT workflow is enhanced by allowing clinicians to quickly contour the tumors and organs at risk in three dimensions, then propagate the organs to alternate 4D datasets to help physicians determine the extent of tumor movement within the patient. This capability opens up the possibility to adapt the daily
treatment plan on the fly."

In addition to MBS and its time-saving benefits, Philips has introduced other workflow enhancements such as P3PC for remote planning, which allows Philips clinical customers to remotely access their patient data at more than 1,600 installed Pinnacle3 sites around the world. While remote patient contouring and treatment planning offer workflow efficiencies today, future adaptive IGRT planning will depend on these remote collaboration tools in order for oncologists to review and interact with their patients' 4D data and daily response to treatment.
