1. An integrated microtomography and optical imaging system, comprising: an imaging chamber adapted to contain an imaging object; a table located within the imaging chamber and adapted to support the imaging object; an optical imaging system located within or about the imaging chamber, the optical imaging system comprising a camera positioned relative to the table such that a first axis extends orthogonally from a surface of the table toward the camera; a microtomography imaging system located within or about the imaging chamber and configured to obtain one or more x-ray images of the imaging object, the microtomography imaging system comprising an x-ray source and an x-ray sensor adapted to receive x-rays from the x-ray source, wherein the x-ray source and the x-ray sensor are aligned along a second axis orthogonal to the first axis; and at least one mirror positioned on the table and comprising a reflective surface oriented at an angle with respect to a surface of the table, wherein the optical imaging system is adapted to obtain a first optical image of the imaging subject by detecting light propagating from the imaging subject to the camera along the first axis, and while the first optical image is being obtained, a second optical image of the imaging subject by detecting light from the imaging subject reflected by the at least one mirror; and wherein the optical images and the one or more x-ray images are both obtained while the imaging object remains within the imaging chamber.
