Radiation treatment planning system and computer program product

摘要

The present invention relates to a radiation treatment planning system and a corresponding computer program product. The system comprises means for graphically displaying an image representing a target area 10 to be treated with a set of therapeutic radiation beams and an adjacent structure comprising healthy tissue 14 and/or organs at risk 12, and for displaying corresponding dose values according to a preliminary treatment plan. The system further comprises means for allowing a user to interactively input a local dose variation, local dose variation means for revising the preliminary treatment plan such as to account for the local dose variation inputted by the user and dose recovery means comprising means for revising the treatment plan again such as to at least partially compensate for a change of dose in a predetermined recovery area caused by said dose variation.
