Solution Approach 1:

The patent segments the calculation process by separating dose volume calculation from dose rate volume calculation. The dose volume is calculated first using traditional Monte Carlo methods, then this result is used as input for the dose rate volume calculation. This segmentation allows the system to reuse computational results and avoid redundant calculations, thereby reducing overall computational time while maintaining accuracy.

Solution Approach 2:

The patent performs preliminary calculation of the dose volume distribution before calculating the dose rate volume. By establishing the dose volume distribution first, the system creates a foundation that simplifies subsequent dose rate calculations. This preliminary action eliminates the need to perform full Monte Carlo simulations twice, significantly reducing computational time while preserving calculation precision.
