Brachytherapy position verification system and methods of use

摘要

In one embodiment, a verification system for confirming the position of a conduit inserted within a patient may include an elongate control element dimensioned for insertion within the conduit. The control element has a proximal end and a distal end, and a verification element coupled to a distal region. The verification element may be configured to detect the presence of a reference marker associated with the conduit and communicate a signal indicative of the position of the reference marker relative to the verification element. The control element may also be configured to maneuver the verification element along a length of the conduit. The system may also include a drive device coupled to a proximal region of the control element for controlling movement of the control element through the conduit, a controller associated with the verification element and configured to communicate with the verification element, and a signal conductor for conducting the signal between the verification element and the controller.
