发明名称 CT SYSTEMS AND METHODS THEREOF
摘要 A CT system and method thereof are discloses. The system includes: a conveyor mechanism; a first scanning stage configured to scan the object and generate a first digital signal; a second scanning stage spaced from the first scanning stage at a preset distance in a direction of the object's movement; 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. The processing device reconstructs a CT image of the object at a second image quality higher than the first image quality at least based on the second digital signal. The system takes full advantage of the distributed ray sources which replace the normal slip ring technology.

主权项 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 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 reconstruct a CT image of the object at a second image quality higher than the first image quality at least based on the second digital signal.
