ABSTRACT:
Endoscopic examining apparatus, particularly useful in MRI, includes a probe movable through the body cavity; a set of tracking coils carried by the probe; and a set of imaging coils carried by the probe. A control system controls the tracking coils to sense and indicate the location and orientation of the probe within the body cavity, and controls the imaging coils to image selected areas within the body cavity. Also described are a novel probe particularly useful in such apparatus, and a novel method of making such probes by a printed circuit technique.
