1. A system, comprising: a shape sensing enabled device comprising at least one optical fiber; a source positioning module configured to receive optical signals from the at least one optical fiber and interpret the optical signals to provide motion information of the shape sensing enabled device, the motion information comprising a shape and a position of the shape sensing enabled device and a position of treatment sources within the shape sensing enabled device at any time during treatment; and a dose determination module configured to provide one or more temporal bins cumulatively equaling a total treatment time, wherein 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 shape sensing enabled device, the dose determination module 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.
