Claim 10:
11. The method of claim 10, further comprising one or more of the following:
(i) preparing the plurality of A-lines, the image, or the images by deleting the imaging probe and extravascular noise from a one frame or a current frame or image or otherwise perform frame or image processing or pre-processing, and setting the counter to zero;
(ii) performing frame or image processing or pre-processing on the A-lines, image, or images, by deleting one or more of: the imaging probe and/or extravascular noise from a current frame or image;
(iii) segmenting the A-lines, the one frame or the current frame, the image, or the images using automatic thresholding, and separating the A-lines, the one frame or the current frame, the image or the images into four equal parts which correspond to four Cartesian quadrants while separating the A-lines, the image, or the images into three or more equal parts;
(iv) deleting any detected object of a predetermined size, and counting how many objects are above or over a specific or predetermined distance from the imaging probe or counting how many objects overlap with the BIA;
(v) deleting any detected object of a predetermined size, counting how many objects are above or over a specific or predetermined distance from the imaging probe or counting how many objects overlap with the BIA, and in a case where at least three (3) objects are detected above or over an imaging probe distance as a specific or predetermined distance from the imaging probe or are not overlapping with the BIA, then performing the counting step by increasing the counter to one or by one, or, in a case where at least three (3) objects are not detected over the imaging probe distance or are overlapping with the BIA, setting the counter again to zero, and moving to the next frame or image such that the steps (c)-(g) are repeated; and/or
(vi) in a case where the counter is not yet equal to or greater than the predetermined value X, then moving to the next A-line frame or image and repeating the importing and the steps (c)-(g), or, in a case where the counter is equal to or greater than the predetermined value X, then triggering the automatic pullback of a catheter or probe of the imaging device via step (h) by ending a signal, by using a signal, or by generating or transmitting a signal.
