  • Radiation treatment planning method and apparatus
    Patent number: 5647663
    Abstract: A method of radiation treatment planning for radiation systems providing multiple beams of independently adjustable intensities limits the iterative beam weight determination to a set of discrete beam weights avoiding errors in post-optimization truncation of the beam weights, and decreasing the iteration time. Those beams having a greatest effect on the solution are preferentially adjusted and larger changes between discrete values of beam weights are given preference to smaller changes.
