July 29, 2009 – Nucletron focused on its Model-Based Segmentation (MBS) module and its VMAT treatment planning solution at the AAPM 51st Annual Meeting taking place from July 26-30 in Anaheim, Calif.

Nucletron is featuring software modules for Model-Based Segmentation (MBS) and treatment planning of Intensity Modulated Arc Therapy (IMAT).

VMAT is a relatively new and 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. This concept enables faster treatment delivery compared to traditional IMRT, where the patient is irradiated only from a few selected angles. At the same time, treatment quality remains similar or can be improved compared with traditional IMRT. The new IMAT treatment planning solution will be integrated in the Oncentra Optimizer module.

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. Traditionally this is a very time-consuming task as the contours are outlined manually. The new Model-Based Segmentation 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 MBS solution will be integrated in the Oncentra Anatomy module and will be useful for treatment planning of both external radiation therapy and brachytherapy.
