1. An integrated microtomography and optical imaging system, comprising: an imaging chamber adapted to contain a separate imaging object therewithin; a rotating table located within the imaging chamber and adapted to support the separate imaging object thereupon, wherein the rotating table is further adapted to rotate the imaging object about a vertical axis running therethrough to a plurality of different rotational positions during a combined microtomography and optical imaging process; an optical imaging system located within or about the imaging chamber, said optical imaging system including a camera positioned substantially vertically above the imaging object and adapted to obtain optical images of the imaging object with respect to the vertical axis while the imaging object is on the rotating table; and a microtomography imaging system located within or about the imaging chamber and configured to obtain x-ray images of the imaging object while the imaging object is on the rotating table, said microtomography imaging system including an x-ray source and one or more x-ray sensors adapted to receive x-rays from the x-ray source, wherein the x-ray source is positioned in a substantially horizontal direction with respect to the imaging object, and wherein the optical images and the x-ray images are both obtained while the imaging object remains within the imaging chamber.
