Zusammenfassung:A computed tomography (CT) system including a scanning unit having an x-ray emitter, a detector arranged to receive x-rays emitted from the x-ray emitter during a scanning operation, and a manipulating unit arranged to rotate an object about a rotational axis and move the object through a plurality of positions along a path, defined by the rotational axis, in between the x-ray emitter and the detector. The CT system can also include a computing device, including a memory storing computer-executable instructions and at least one data processor. The processor is arranged to execute the instructions, which cause the processor to perform operations including: receiving, from the scanning unit, first data characterizing the path, and receiving, from the scanning unit, second data characterizing the one or more x-ray images of the object at at least one position of the plurality of positions, determining a compensation to be applied to the second data based on the first data, reconstructing an image of the object based on the first data, the second data, and the compensation, and providing the reconstructed image.
