2. The center line should be aligned with the center line of the grid, and the left and right deviation should not exceed 3cm;
3. When using grid photography, when the X-ray tube needs to be tilted, the tilt direction must be consistent with the direction of the lead strip, otherwise the X-ray and the lead strip will be absorbed at an angle;
