Claim 9:
10. The system of claim 1, wherein the one or more processors further operate to one or more of the following:
detect the one or more of the lumen edges, the guide wire, the one or more stents or stent struts, and/or one or more other artifacts in polar coordinate images or the polar coordinate image data, based on the information on each A-line, and then using neighbor A-line information to group or classify the detected one or more of the lumen edges, the detected guide wire, the detected one or more stents or stent struts, and/or the detected one or more other artifacts into objects or object types;
extract the objects from the polar coordinate images in such a manner that levels of layers are identified and a next level of results has a lesser or smaller region of interest to work with and has a confidence or additional confidence of the grouped or classified objects or object types; and/or
performing processing in, or adopting, an iterative manner to add information on extracted objects on each A-line, and to fully cover all A-lines and objects that can be detected in the polar coordinate images.
