1. A hybrid computerized tomography (CT) scanner comprising:
a first x-ray source that directs a first x-ray attenuation to an energy integrating detector, wherein the energy integrated detector is dimensioned to produce an image of a predetermined area of a patient;
a second x-ray source that directs a second x-ray attenuation to a photon counting detector, where the photon counting detector to produce an image of a specific tissue target within the predetermined area;
a processor to produce a final CT image based on the image of the predetermined area of the patient and the image of the specific tissue target within the predetermined image,
wherein the processor is configured to analyze tissue types, the analysis comprising:
selecting a process among a plurality of processes to analyze the final CT image based on an expected soft tissue type; and
segmenting the processed final CT image to display the soft tissue.
