Abstract :
Batho correction algorithm has high correction accuracy in relatively homogeneity tissue, but has low accuracy in cavum region and the interface between different density tissues, which can´t meet the accuracy requirement of clinical application. In this paper, the changes of dose distribution with every kinds of different density tissues combination are researched by Monte Carlo (MC) simulation, the database of dose distribution on non-uniform tissue is built up for the purpose of development fast and accurate dose calculation method.
