MOTION-COMPENSATED DOSE RECEIVED BY TISSUE IN HIGH DOSE RATE BRACHYTHERAPY PROCEDURES

摘要

A system and method include a shape sensing enabled device (116) having at least one optical fiber (118). A source positioning module (124) is configured to receive optical signals from the at least one optical fiber within a structure and interpret the optical signals to provide motion information of treatment sources within the device. A dose determination module (130) is configured to provide one or more temporal bins representing a total treatment time. For each temporal bin, the dose determination module is configured to determine a dose received by a target area to be treated using the motion information of the treatment sources. The dose determination module is further configured to combine the dose received by the target area for each of the one or more temporal bins to determine a total dose received by the target area.
