Patent ID: 8849375

Claim:
An ultrasound catheter system supporting orientation and display of intra-vascular ultrasound imaging data, comprising: one or more imaging devices configured to perform image acquisition of the patient anatomy; an ultrasound catheter configured to be placed in the patient anatomy and acquire ultrasound images, the catheter comprising: a body having a pattern of radio-opaque material, said pattern: varying with angular rotation of said catheter; and indicating an angle of rotation of a predetermined reference orientation of said catheter relative to a reference location, so that an X-ray image of said catheter body indicates said pattern and said pattern is analyzable by an image data processor to determine said angle of rotation; and an image data processor configured to automatically analyze said X-ray image to identify a distance between a proximal end of the pattern and an intersection point of an edge of the pattern and an axis of said catheter; and said image data processor uses said distance in determining said angle of rotation.
