Royal Philips Electronics today announced the release of its Model Based Segmentation (MBS) software for image guided radiation therapy (IGRT) workflow enhancement. The MBS software is an upgrade of the company’s Pinnacle3 Radiation Therapy Planning system and will be showcased this week at the 48th Annual Meeting of the American Association of Physicists in Medicine (AAPM) in Orlando, Fla.
Philips’ Pinnacle3 system combines AcQSim3 simulation, Syntegra image fusion and P3IMRT modules to provide an oncology toolbox capable of sculpting radiation doses to tumors. The new MBS software is designed to reduce the time it takes to contour tumors and anatomical structures and is a move towards more quickly adapting patients' treatment plans based on their response to daily treatment, Philips said.
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 has introduced other workflow enhancements such as P3PC for remote planning, the company said.
The company also has added new features to its Brilliance CT Big Bore system with an oncology configuration designed specifically for use in radiation oncology. New 4D tools have been added to the Philips-exclusive Tumor LOC application, allowing the user to assess motion of respiratory correlated studies. The ability to review patients' breathing patterns and easily draw contours encompassing the range of motion over the entire respiratory cycle simplifies this complex procedure. Advanced 4D tools such as dynamic digitally reconstructed radiographs (DRR) and digitally composited radiographs (DCR) allow visualization of respiratory motion from a beam's eye view perspective, Philips said.
The interconnected Brilliance Workspace allows users to easily evaluate multi-phasic volumetric datasets. With new evaluation tools such as intensity projections over time, dynamic slab viewing and user-defined phase selections, novel treatment options are now possible.
Extended display field of view is another new enhancement debuting at the AAPM meeting. Provided at the request of clinicians, extended display field of view allows users to visualize outside the standard true 60cm SFOV to help avoid untargeted areas during treatment planning.
