Abstract:
A method for acquiring high-quality images of a desired structure having periodic motion in a series of images comprising the steps of:a) displaying the series of images to accept user-supplied input identifying a selected image containing the desired structure as a reference image R;b) identifying a region of interest ROI1 in reference image R encompassing the desired structure;c) cross-correlating ROI1 with each of the other images from the series of images to result in a series of cross-correlation images;d) defining a second region of interest ROI2 centered in each cross-correlation image;e) identifying images as ""usable"" images, which have a peak within ROI2 of their cross-correlation image more than a predetermined distance away from an edge of ROI2;f) processing only the ""usable"" images, to result in a higher quality processed image.
