Abstract
This paper analyzes the recalculation of plans for the exposure of patients with tumors of the lung, head and neck by the Monte Carlo method. There are presented the results of calculations with understating the dose by 29% when using the algorithm Ray-Tracing. It is proposed mandatory recalculation of dose by Monte Carlo method in planning exposure for patients with tumors of the lung and head and neck tumors to eliminate significant systematic errors in the values of input dose.References
