RaySearch, Nucletron to Develop Two New Treatment Planning Solutions

January 21, 2009 - RaySearch Laboratories AB and Nucletron BV have are extending a development and licensing agreement for Raysearch to 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.

The new VMAT treatment planning solution will be integrated in the Oncentra Optimizer module of MasterPlan. VMAT, an advanced form of Intensity Modulated Radiation Therapy (IMRT), in which the target is continuously irradiated while the source of the beam rotates around the patient in single or multiple arcs.

MBS facilitates the segmentation process when three-dimensional models of the tumor and surrounding organs at risk are created prior to the treatment planning process. The new Model-Based Segmentation software module uses three-dimensional organ models that automatically adapt to patient image data.

Combined with interactive tools, this solution is designed the to decrease the time spent on segmentation and also improve consistency in the process. 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.
