A system and method for CT image acquisition with increased slice acquisition and minimal image data degradation is provided. The system includes an x-ray projection source positioned that projects a cone beam of x-rays from a focal spot of the x-ray projection source toward an object and a plurality of detector modules positioned on the rotatable gantry to receive x-rays attenuated by the object. Each of the detector modules includes a module frame having a top surface that includes a plurality of facets formed thereon constructed so as to be oriented at differing angles relative to the focal spot and 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, with each sub-module being oriented at an angle relative to the focal spot based on a respective facet on which the sub-module is mounted. |
