Outline of Final Research Achievements |
We developed random variable (RV) approach to calculate Tumor Control Probability (TCP) of inhomogeneous radiation dose distribution, using computer simulation to count surviving cells after radiotherapy using random variables. Considering the variance of surviving probability, TCP is worse with increasing the variance of surviving probability. The effect is less when the surviving probability is changed in each irradiation. We also confirmed that RV approach is able to calculate TCP adequately if dose distribution of tumor is inhomogeneous.
