Patent ID: 8824625

Claim:
A computed tomography scanning system for recording computed tomography image data of an object in an object area, the system comprising: an X-ray source and an X-ray detector at either side of the object area, the X-ray source being configured for emitting X-rays and the X-ray detector comprising a stack of elongated detector array arrangements arranged in parallel separated from one another and being configured for detecting X-rays from the X-ray source transmitted through the object, thus recording images of the object; a device configured for rotating the X-ray source and the X-ray detector with respect to the object around an axis of rotation which is parallel with the elongated detector array arrangements arranged in parallel, while the elongated detector array arrangements are configured for imaging the object repeatedly; a multi slot collimator between the X-ray source and the object area to create thin essentially planar sheets of radiation, which impinge on the elongated detector array elements; and a device configured for moving the elongated detector array arrangements within the X-ray detector during the rotation of the X-ray source and the X-ray detector with respect to the object, thus allowing the elongated detector array arrangements to record the computed tomography image data of the object, wherein the device for moving the elongated detector array arrangements within the X-ray detector moves the elongated detector array arrangements linearly in a direction (y) perpendicular both to the optical axis (x) of the X-ray detector and to the axis of rotation (z) during the rotation of the X-ray source and the X-ray detector with respect to the object.
