Abstract
An imaging system is provided with an ultrasound catheter and a controller coupled to the ultrasound catheter. The catheter includes a localizer sensor configured to generate positional information for the ultrasound catheter, and an imaging ultrasound sensor having a restricted field of view. The controller co-registers images from the imaging ultrasound sensor with positional information from the localizer sensor.

18. A medical apparatus for co-registering x-ray and ultrasound images, comprising:
a controller configured to; establish a frame of reference with an x-ray imaging source; determine a location of an ultrasound imaging catheter within the frame of reference; receive an x-ray image containing the ultrasound imaging catheter and a tissue surrounding the ultrasound imaging catheter; receive at least one ultrasound image of the tissue from the ultrasound imaging catheter; co-register the x-ray image with at least one ultrasound image from the ultrasound imaging catheter; and generate on a display device a graphical representation including the x-ray image from the x-ray imaging source, the at least one ultrasound image from the ultrasound imaging catheter, and a visual indicator corresponding to the co-registration of the x-ray image with the at least one ultrasound image. - View Dependent Claims (19, 20, 21, 22, 23, 24)

25. A method for imaging tissue within the body of a patient, comprising:
-
establishing a frame of reference with an x-ray imaging source; determining a location of an ultrasound imaging catheter within the frame of reference; receiving from the x-ray imaging source an x-ray image containing the ultrasound imaging catheter and a tissue surrounding the ultrasound imaging catheter; receiving from the ultrasound imaging catheter at least one ultrasound image of the tissue; co-registering the x-ray image with the at least one ultrasound image from the ultrasound imaging catheter; and outputting to a display device a graphical representation including the x-ray image, the at least one ultrasound image, and a visual indicator corresponding to the co-registration of the x-ray image with the at least one ultrasound image. - View Dependent Claims (26, 27, 28, 29, 30)

31. A system for co-registering x-ray and ultrasound images of a patient'"'"'s body, the system comprising:
-
a field emitter configured to generate an electrical field within the body; an ultrasound imaging catheter, comprising; an elongate body including a proximal section and a distal section; at least one annular ultrasound imaging sensor disposed on the distal section of the elongate body and configured to image tissue within a field of view surrounding the ultrasound imaging catheter; and a plurality of positional sensors configured to sense the electrical field generated by the field emitter; and a controller adapted to couple to the field emitter, the ultrasound imaging catheter, and an x-ray imaging source, wherein the controller is configured to; establish a frame of reference with the x-ray imaging source; determine a location of each of the plurality of positional sensors within the frame of reference; receive an x-ray image containing the ultrasound imaging catheter and the tissue surrounding the ultrasound imaging catheter; receive at least one ultrasound image of the tissue from the ultrasound imaging catheter; and co-register the x-ray image with the at least one ultrasound image from the ultrasound imaging catheter. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40)
