METHODS AND APPARATUS FOR EXTERNAL BEAM RADIATION TREATMENTS OF RESECTION CAVITIES

摘要

Apparatus and methods for external beam radiation treatments of resection cavities are described. One embodiment of such an apparatus comprises a stabilization device having an expandable member configured to (a) be implanted in a patient and (b) move from a first position for insertion into a resection cavity within the patient to a second position for stabilizing tissue of the cavity. The apparatus further includes an active marker coupled to the stabilization device and an electrically conductive line connected to the active marker. The active marker is configured to transmit a signal. The electrically conductive line has an internal portion coupled to the stabilization device and an external portion configured to be coupled to a signal generator and/or a signal processor located outside of the patient.
