Objectives: A sharp dose fall-off is very important because of the high dose applied on fewer fractions in radiosurgery treatment planning. However, there is not any parameter expressing the dose fall-off on a certain direction(s). The aim of the present study is to define a numerical preservation index of the critical tissues. This would allow an objective comparison of the treatment plans. The Critical Organ Based Gradient Index (CGI) numerically defines the dose fall-off that is specific to…
