The present invention relates to a CT scanner comprising:a rotor rotatable about an axis of rotationan X-ray source mounted to the rotor having a focal spot from which an X-ray beam emanatesan X-ray detector array comprising a plurality of X-ray detectors for detecting X-rays in the X-ray beam that have been attenuated by an imaged body,wherein the detector array has at least one high resolution region in which detectors have a high packing density and at least one low resolution region in which detectors have a low packing density,wherein the at least one low resol uti on area is displaced from the at least one hi gh resol uti on area along a direction perpendicular to the axis of rotation, andwherei n the at least one low resol uti on regi on together wi th the at least one hi gh resol uti on region define a field of view of the CT scanner.
