Abstract
A method for planning an intensity modulated radiation therapy system comprising outlining a 3D target volume, providing relative radiation intensities of the 3D, a) selecting specific beam directions for the system to use and b) optimizing the system using an arcing paradigm; back-projecting the given intensities to the selected beam entry portals; sub-dividing each entry portal into discrete dose elements; applying thereto a cost function that scores the goodness of the plan by positively rewarding doses in selected regions and negatively rewarding doses in protected regions, and adjusting the weights of each of the dose elements to increase the overall score.
