Abstract:
1. A method for calculating a radiation dose distribution of a radiation beam for a radiation treatment system for the purpose of radiation therapy of an animal body, wherein said radiation beam of the radiation treatment system exhibits a size and a shape of a specific beam field at different depths, wherein the method is characterized by the steps of: i) determining one beam quality index being representative for said radiation beam being used, and ii) calculating said radiation dose distribution in said specific beam field using parameterized dose deposition kernels based on said one beam quality index; iii) using for different devices pre-collected measured radiation beam data, said measured radiation beam data comprising: iv) determining said one beam quality index according to step i) using the pre-collected measured radiation beam data according to step iii); v) expressing the dose deposition kernel parameters as a mathematical function of said one beam quality index being determined.
