50. A system for localizing lesions in a body lumen, the system comprising:
-
a catheter body comprising a proximal and distal portion;
at least one detector that can obtain information about the lesion;
a plurality of markers positioned on the distal portion of the catheter that allow a user to track the azimuthal orientation of the distal portion of the catheter body; and
a computer that superimposes the information obtained by the detector on an anatomic image of the body lumen. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57, 59, 60, 61)

58. A system for displaying an anatomic image of a body lumen, the system comprising:
-
an imaging device that can acquire an anatomic image of the body lumen;
a detecting device to obtain information of a marked lesion in the body lumen; and
a computer configured to store the anatomic image(s) of the body lumen, wherein the computer receives the information from the detecting device and displays the information on the stored anatomic image.
