Claim 11:
12. The method of claim 9, further comprising one or more of the following:
(i) acquiring a next frame of the region of interest (ROI), or using the region of interest (ROI) shown or as in the reference frame as a reference region of interest (ROI) and having values from the reference frame being indicative of a possible preclearing image;
(ii) identifying a first frame of the region of interest (ROI);
(iii) storing the first frame as an original image of the region of interest (ROI);
(iv) storing the first frame as an original image of the region of interest (ROI) in a memory;
(v) computing or determining the clearance metric, the clearance metric including a comparison of data, or intensity value(s), for one or more frames of the region of interest (ROI) with data, or intensity value(s), for the reference frame, or the clearance metric operating to measure the amount of, or the level in, the change; and/or
(vi) determining that the clearance metric is not above the threshold, then returning to acquire a next frame of the region of interest (ROI), and computing or determining a new clearance metric until the clearance metric is above the threshold.
