A method and apparatus for stereotaxic placement of probes in the body utilizing CT scanner localization

摘要

The method and apparatus are presented which allow for CT guided biopsies of the body. The method is based on the finding of a reference point on the patient's body that exactly correlates to a point on the CT scan. This is accomplished by means of a localization device placed on the patient's skin which can be identified in cross section on the CT scan. Measurements of the localization device on CT scan can then be correlated to the device on the patient.
