Claim 11:
12. The method of claim 11, wherein one or more of the following:
(i) the method further comprises 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, and the object of the predetermined size is at least one of the following: a small object; and/or is an object corresponding to noise, residual blood, and/or other artifact(s);
(ii) the method further comprises 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, and the specific or predetermined distance from the imaging probe is defined as imaging probe distance, and the method further comprises comparing the objects to the imaging probe distance value to decide whether the objects belong to blood or not;
(iii) the method further comprises 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, and/or to define an imaging probe distance as a specific or predetermined distance from the imaging probe, the method further comprises measuring an imaging depth at different blood state images or frames, and averaging measurements; and/or
(iv) the method further comprises 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, and the specific or predetermined distance is defined by using images with blood presence.
