The method includes establishing first and second parallax scanning points of view and overlapping fields of view of a subject volume including a region of interest. The method includes reading at least one scene parameter associated with the field of view of the subject volume. The method includes determining stereoscopic and parallax scanning setting based on a value(s) derived from at least one scene parameter. The method also includes computer generating and storing virtual parallax scanning stereoscopic imagery. ## Claims ### Claim 1 A computer-implemented method of stereoscopic imaging using two separate parallax scanning points of view, comprising: establishing a first point of view of a first parallax scanning optical device of a first stereoscopic camera, a second point of view of a second parallax scanning optical device of a second stereoscopic camera, and a field of view of a subject volume based on an overlap of the first point of view and the second point of view and including a region of interest, wherein the field of view of the subject volume is determined based on a first focal length of the first stereoscopic camera and a second focal length of the second stereoscopic camera;
