Claim 1:
2. The device of claim 1, wherein the one or more processors further operate to one or more of the following:
(i) prepare the plurality of A-lines, the image, or the images by deleting the imaging probe and extravascular noise from a current frame or image or otherwise perform frame or image processing or pre-processing, and set the counter to zero;
(ii) perform 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) segment the A-lines, a one frame or a current frame, the image, or the images using automatic thresholding, and separate 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) delete any detected object of a predetermined size, and count how many objects are above or over a specific or predetermined distance from the imaging probe or count how many objects overlap with the BIA;
(v) delete any detected object of a predetermined size, and count how many objects are above or over a specific or predetermined distance from the imaging probe or count how many objects overlap with the BIA and in a case where at least three (3) objects are detected above or over the imaging probe distance as the specific or the predetermined distance or are not overlapping with the BIA, then perform 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 above or over the imaging probe distance or are overlapping with the BIA, set the counter again to zero, and move to the next frame or image such that the one or more processors operate to repeat the steps (c)-(g); and/or
(vi) in a case where the counter is not yet equal to or greater than the predetermined value X, then move to the next A-line frame or image and repeat 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 trigger 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.
