Check the horizontal and vertical position of the column, if it is not flat, adjust the fixing screw at the top of the column to correct it. Check the installation accuracy of the X-ray tube beam limiter. Check the balance weights on both ends of the U-arm at all times. If necessary, the X-ray tube beam limiter assembly inspection detector should be reinstalled, first in the horizontal position and then in the vertical position. The position of the detector can be moved up and down by adjusting the screws on the side of the detector assembly. Rotate the U-arm to the vertical position and turn on the beam limiter field light so that the center of the light range points to the central anchor point on the upper surface of the detector. And the projection coordinate lines of the light in the horizontal and vertical directions should be consistent with the area range indicator on the upper surface of the detector. Adjust the alignment and safety screws at the four corners of the beam limiter to match.
Place the X-ray beam alignment inspection tool on the beam limiter inspection tool and observe the X-ray beam alignment inspection carefully. Tools are projected on it at the same scale. Check the acquired image and adjust the upper spherical marker to the center. Adjust the center of the X-ray irradiation field and the image receiving assembly, display the acquired image, and check the deviation of the X-ray irradiation field from the center of the flat panel detector. In this way, the problem of deviation of the influence of the bea of the X-ray machine is solved.
