Claim 2:
3. A method for automatically positioning CT equipment, which comprises: installing a calibration bead in front of the window of X-ray tube of a CT equipment; initiating the CT equipment to irradiate the calibration bead by X-ray to project a first calibration image on an X-ray detector; obtaining a coordinate of the first calibration image on the X-ray detector by an image processing unit and calculating a displacement vector from the coordinate to the center of the X-ray detector; calculating the displacement vector by an image processing unit to generate a calibration instruction for driving a control module to adjust the position of the X-ray detector, so that the center of the X-ray detector overlaps with the first calibration image; obtaining a second calibration image of the calibration bead; and confirming that the second calibration image is exactly overlapping with the center of the X-ray detector for completing positioning.
