Abstract
A method and apparatus for determining an optimized radiation beam arrangement for applying radiation to a tumor target volume while minimizing radiation of a structure volume in a patient, which uses an iterative cost function based on a comparison of desired partial volume data, which may be represented by cumulative dose volume histograms and proposed partial volume data, which may be represented by cumulative dose volume histograms for target tumors and tissue structures for delivery of the optimized radiation beam arrangement to the patient by a conformal radiation therapy apparatus.
