Abstract:

A method for displaying real-time imagery of coronary arteries including a chronic total occlusion (CTO) includes acquiring three-dimensional image data of coronary arteries using a three-dimensional medical imaging device, wherein the three-dimensional image data includes imagery of the CTO. A radiocontrast agent is administered to a patient. Real-time image data of the coronary arteries are acquired using one or more fluoroscopes. The real-time image data does not include imagery of the CTO and down-stream vessel structure. The three-dimensional image data is co-registered with the real-time image data using an image processing device within a vicinity of the CTO. The co-registered image data are displayed in real-time using a display device to accurately illustrate the location of the CTO within the context of the real-time image data.
