1. A method for performing co-registration between one or more image frames and one or more images, the method comprising:
acquiring, obtaining, or receiving one or more images acquired in one or more imaging procedures in which an imaging probe or catheter is inserted into a predetermined target area of an object or subject;
obtaining or receiving one or more images or image frames to be co-registered with the one or more images;
obtaining, receiving, or determining timing information indicating a timing when the one or more images or image frames are acquired with respect to the one or more imaging procedures;
determining a process for co-registration between the one or more images and the one or more images or image frames, based on the obtained, received, or determined timing information;
applying the determined process for co-registration to the obtained images and the obtained one or more images or image frames;
selecting an image or image frame from one or more first images or image frames including a flushing media or agent and/or a contrast media and selecting an image or image frame from one or more second images or image frames not including a flushing media or agent and/or a contrast media having identical cardiac phase signals; and
in a case where it is determined that a detected path of the imaging probe or catheter of the image or image frame from the one or more second images or image frames is not located within a contour of the predetermined target area of the image or image frame from the one or more first images or image frames, selecting another image or image frame from the one or more second images or image frames at an identical cardiac phase signal, overlaying the image or image frame from the one or more first images or image frames with the another image or image frame from the one or more second images or image frames to determine whether the detected path of the imaging probe or catheter of the another image or image frame from the one or more second images or image frames is located within the predetermined target area contour of the image or image frame from the one or more first images or image frames, and determining whether a marker associated with or detected in the image or image frame from the one or more first images or image frames is located on the detected path of the imaging probe or catheter of the another image or image frame from the one or more second images or image frames in response to a determination that the detected path of the imaging probe or catheter of the another image or image frame from the one or more second images or image frames is located within the predetermined target area contour of the image or image frame from the one or more first images or image frames.
