TREATMENT PLAN OPTIMIZATION METHOD FOR RADIATION THERAPY
摘要
A treatment planning method and system for optimizing a treatment plan used to irradiate a treatment volume including a target volume, such as a tumor, is disclosed. In accordance with the present invention, gradients of a cost function that defines a treatment volume arc back projected to a surface of interest. The method and system of preferred embodiments of the present invention calculate the gradients with respect to the dose received by the treatment volume. Machine parameters that are associated with the surface of interest may then be optimized based on the back projected gradients.
