Patent ID: 8204171

Claim:
A CT system comprising: a rotatable gantry having an opening to receive an object to be scanned; an x-ray projection source positioned on the rotatable gantry that projects a cone beam of x-rays from a focal spot of the x-ray projection source toward the object; and a plurality of detector modules positioned on the rotatable gantry and configured to receive x-rays attenuated by the object, wherein each of the plurality of detector modules comprises: a module frame having a top surface that includes a plurality of facets formed thereon, wherein the plurality of facets are constructed so as to be oriented at differing angles relative to the focal spot; a plurality of sub-modules positioned on the plurality of facets to receive the x-rays attenuated by the object and to convert the x-rays to electrical signals, wherein each sub-module is oriented at an angle relative to the focal spot based on a respective facet on which the sub-module is mounted; and a data acquisition system (DAS) connected to the plurality of sub-modules to receive the electrical signals therefrom.
