Patent ID: 8208701

Claim:
A method for creating a high-resolution image of an object in an angiographic image of a patient, comprising: recording at least two images of the object and a catheter combination including catheter markers; detecting a region of interest in an area between the markers completely containing the object in the at least two images; marker-based coarsely registering the region of interest by registering the markers in the at least two images; non-marker-based finely registering the region of interest by registering a content of the region of interest in the at least two images after the marker-based coarse registration to increase a surface of the object on a total surface of the region of interest for generating a fine-registered image; and creating the high-resolution image of the object by arithmetically averaging across the fine-registered image, wherein the fine registration is undertaken by a method selected from the group consisting of: sum of difference squares, variance of difference, leading-sign-change based measuring, coincident bit counting, and difference-histogram-based measuring.
