According to a new development and licensing agreement, RaySearch will develop software modules for Model-Based Segmentation (MBS) and treatment planning of Volumetric Modulated Arc Therapy (VMAT) for Oncentra MasterPlan, Nucletron’s multimodality treatment planning system.
VMAT is a relatively new and advanced form of intensity modulated radiation therapy, in which the target is continuously irradiated while the source of the beam rotates around the patient in single or multiple arcs. The new VMAT treatment planning solution will be integrated in the Oncentra optimizer module of MasterPlan.
The new MBS software module uses three-dimensional organ models that automatically adapt to patient image data. Combined with highly intuitive interactive tools, this solution has the potential to significantly decrease the time spent on segmentation and also improve consistency in the process, the two companies said.
The MBS solution will be integrated in the Oncentra anatomy module of MasterPlan and will be useful for treatment planning of both external radiation therapy and brachytherapy.
Jos Lamers, CEO of Nucletron, said: “Oncentra MasterPlan represents the latest generation of treatment planning solutions. With the addition of VMAT support as well as a new, time-saving method for semi-automatic target definition, we believe that Oncentra MasterPlan will secure its position as the most advanced linac-independent treatment planning system on the market.”
