Claim:
1. A Computed Tomography (CT) system, comprising: a conveyor mechanism configured to convey and move an object under inspection linearly; a first scanning stage comprising a first ray source, a first detector, and a first data acquisition device, and configured to scan the object and generate a first digital signal; a second scanning stage configured to be spaced from the first scanning stage at a preset distance in a direction of the object's movement, and comprising a second ray source, a second detector, and a second data acquisition device; a third scanning stage comprising a third ray source, a third detector, and a third data acquisition device; a processing device configured to reconstruct a CT image of the object at a first image quality based on the first digital signal, and analyze the CT image; and a control device configured to adjust a scanning parameter of the second scanning stage based on an analysis result of the processing device to cause the second scanning stage to output a second digital signal, wherein the processing device is further configured to reconstruct a CT image of the object at a second image quality higher than the first image quality at least based on the first digital signal and the second digital signal; wherein the control device is further configured to adjust a scanning parameter of the third scanning stage based on the CT image of at least the first image quality to cause the third scanning stage to output a third digital signal, and wherein the processing device is further configured to reconstruct a CT image of the object at a third image quality higher than the first image quality at least based on the first digital signal, the second digital signal, and the third digital signal.
