A system and method for CT image acquisition with increased slice acquisition and minimal image data degradation is provided. The system (10) includes an x-ray projection source (14) positioned that projects a cone beam of x-rays (16) from a focal spot (15) of the x-ray projection source (14) toward an object (22) and a plurality of detector modules (20) positioned on the rotatable gantry (12) to receive x-rays attenuated by the object (22). Each of the detector modules (20) includes a module frame (52) having a top surface (56) that includes a plurality of facets (58) formed thereon constructed so as to be oriented at differing angles relative to the focal spot (15) and a plurality of sub-modules (60) positioned on the plurality of facets (58) to receive the x-rays attenuated by the object (22) and to convert the x-rays (16) to electrical signals, with each sub-module (60) being oriented at an angle relative to the focal spot (15) based on a respective facet (58) on which the sub-module (60) is mounted. |
