1Measurement precision
If traditional Monte Carlo particle transport simulations are used to calculate radiation dose volume and dose rate volume, then calculation accuracy is maintained, but computational cost increases and calculation time extends
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.
2Reliability
If traditional dose volume and dose rate volume calculations are performed separately, then comprehensive treatment plan assessment is achieved, but computational complexity increases
Solution Approach 1:
The patent merges the dose volume calculation and dose rate volume calculation into an integrated computational framework. By combining these two assessment processes, the system eliminates redundant computational steps and shared calculation routines. The merged approach maintains comprehensive treatment plan assessment quality while reducing overall computational complexity through resource sharing and coordinated processing.
