摘要:
Method and system fiducials contained in removable a device for use in guided radiation therapy treatment. One embodiment includes an active marker configured to be pre-loaded into a catheter for removeably implanting in the tissue of a patient. Another embodiment of the implantable device includes a stability element coupled to the marker and further coupled to an explant line. In some embodiments, the stability element is configured to hold the marker at a fixed location within the catheter (e.g., known location) with respect to a target in the tissue. In other embodiments, the explant line has a first portion coupled to the marker and/or the stability element and a second portion configured to be at least proximate to the dermis of the patient.
