A method for verifying treatment times for simple high-dose-rate endobronchial brachytherapy procedures.

An empirical method for verifying the total treatment time for either a one- or a two-catheter high-dose-rate procedure has been developed. The method can be performed quickly and allows for easy verification of the accuracy of the treatment time arrived at by a computerized planning system. The method is designed to confirm the treatment time to within 10%.
