Conclusion:

Using a new method for accumulation of DVHs based on assumptions of correlation between fractions, we improved upon existing schemes in the high dose region. In this work, a very simple copula function was used; better correspondence at all dose levels may be achieved with a more fitting copula function. The differences between the methods are small but would likely be greater if more than two fractions were accumulated.
