Abstract: A computed tomography scanner may include a component mounting assembly, an x-ray tube, a filter assembly, and a detector assembly. The filter assembly filters an x-ray fan or cone beam generated by the x-ray tube such that the x-ray beam comprises a high dose portion and one or more low dose portions. The filter assembly reduces the photon count of the low dose portions. The x-ray tube may be coupled to the component mounting assembly at a first end and the detector assembly coupled at a second end that is opposite from the first end. The component mounting assembly is rotatable about a rotation axis. The detector assembly includes an array of individual detector elements capable of detecting x-ray photons of the x-ray beam. The high dose portion strikes a high resolution region of the detector assembly and the low dose portion strikes a low resolution region of the detector assembly.
