1. A system for creating a tomographic image of a target volume of an object, the system: comprising: an x-ray source configured to direct x-ray radiation into the object; an x-ray detector configured to detect x-ray radiation transmitted through the object; a light source configured to direct light into the object; a light detector configured to detect light transmitted through and/or emitted from the object, wherein the x-ray source, the x-ray detector, the light source, and the light detector are disposed about an imaging chamber into which the object is placed; a memory for storing code that defines a set of instructions; and a processor for executing the set of instructions to create the tomographic image of the target volume of the object, the tomographic image based at least in part on the detected x-ray radiation and the detected light.
