PROBLEM TO BE SOLVED: To provide method and device allowing the calculation of a radiation dose distribution of a radiation treatment system using a limited amount of data while required accuracy is maintained. SOLUTION: This invention provides a method for calculating a radiation dose distribution for a radiation treatment system for the purpose of radiation therapy of an animal body, wherein the radiation beam of the radiation treatment system exhibits a specific beam field size and shape at different depths, as well as a device for calculating the radiation dose distribution for a radiation treatment system for the purpose of radiation therapy of an animal body, wherein the radiation beam of the radiation treatment system exhibits a specific beam field size and shape at different depths. This method includes: (i) a process of determining at least one beam quality index representing the radiation beam being used; and (ii) a process of calculating the radiation dose distribution in the specific beam field using parameterized dose deposition kernels based on at least one beam quality index.
