  • (a) establishing a location of the body in such a manner as to establish the location of the body even when the body moves;

    (b) inserting at least one catheter into a portion of the body, said at least one catheter including a first location implement;

    (c) using an imaging instrument for imaging said portion of the body;

    (d) establishing a location of said imaging instrument;

    (e) advancing said at least one catheter to at least one point-of-interest in said portion of the body and via a locating implement recording a location of said at least one point-of-interest; and

    (f) displaying and highlighting said at least one point-of-interest in context of an image of said portion of the body, said image being generated by said imaging instrument;

    such that, in course of said procedure, said locations of said body, said at least one catheter and said imaging instrument are known, thereby said at least one point-of-interest is projectable and displayable in context of said image even in cases whereby a relative location of said body and said imaging instrument are changed.
