摘要： The present invention relates to the field of radiation therapy. In particular, the present invention relates to methods for treatment planning for a radiation therapy system. The method includes setting a number of objectives reflecting clinical criteria are set for the regions of interest and generating radiation dose profiles to be delivered to these regions of interest. A convex optimization function for optimizing the delivered radiation based on the objectives is provided and dose profiles for specific treatment configurations including beam shape settings for the radiation dose profiles are calculated using the convex optimization function. Treatment plans including determining the radiation dose profiles to be delivered during treatment based on the treatment configurations are created and an optimal treatment plan that satisfies the clinical criteria is selected.
