PURPOSE We are developing a system to model the effect of random and systematic geometric errors on radiotherapy delivery. The purpose of this study was to investigate biologic and physical fractionation effects of random geometric errors and respiration motion and compare the resulting dose distributions with Gaussian blurring of the planned dose. MATERIALS AND METHODS A hypothetical dose distribution with Gaussian penumbra was used. Random errors drawn from a normal distribution, optionally… CONTINUE READING
