1. An imaging system, comprising:
- an ultrasound catheter including a tubular body, comprising;
a localizer sensor adapted and configured to generate positional information for the ultrasound catheter; and
an imaging ultrasound sensor positionable relative to the tubular body so as to have a first restricted field of view; and
a controller coupled to the ultrasound catheter for co-registering images from the imaging ultrasound sensor with positional information from the localizer sensor, wherein the first restricted field of view spans less than 360 degrees about the tubular body.

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.

15. A method of displaying medical images from a catheter-based imaging ultrasound sensor having a first restricted field of view, the method comprising:
-
generating at least one image with the imaging ultrasound sensor;
calculating a position of the imaging ultrasound sensor;
coregistering the calculated position with the at least one generated image; and
displaying the at least one generated image based on the calculated positional information, wherein the first restricted field of view spans less than 360 degrees about a body of the catheter. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
