Probe holder for stereotactic surgery in the CT scanner. A technical note.

The necessity for intraoperative computer tomographic (CT) visualization of stereotactic probes and for the immediate assessment of the results of therapeutic intervention has brought about the integration of CT and stereotactic surgical sites. In order to perform intraoperative CT imaging, a simple mechanical device has been developed to hold a probe at the target. This device replaces the conventional semicircular arc that was used to guide the probe to the target during stereotactic procedures. Intraoperative imaging during a CT stereotactic procedure was accomplished without significant artifacts.
