Abstract: A multi-modality imaging system is disclosed. The multi-modality system includes a Single Photon Emission Computed Tomography (SPECT) device; and a computed tomography (CT) device operatively connected to the SPECT device. A cradle is operatively connected to the SPECT device and the CT device, wherein the cradle is configured to move through the SPECT and the CT device. The cradle is configured to receive a specimen, wherein the specimen has received a plurality of radioactive isotopes. The plurality of radioactive isotopes is configured to emit a plurality of photons when the specimen is in the SPECT device. The SPECT device is configured to distinguish between the plurality of photons. The plurality of photons is utilized to generate a plurality of images relating to a plurality of compositions of the specimen.
