The convergence line of the X-ray grid is not in a state of coincidence X-ray grid

The convergence line of the X-ray grid is not in a state of coincidence, or the X-ray grid is placed within the specified focal length range, the original emission line will lose too much, and the focus will deviate from the convergence line.X-ray grids need to pay attention to the focal point of the X-ray tube coincides with the convergence line to make the radiation direction of the original emission line consistent with the lead strip direction and pass through the X-ray grid. The greater the difference between the focal length and the focal length, the greater the loss of the original emission line. It is also necessary to pay attention to the distance between the focal point and the film box. At this time, it is called the focal length for short. The focal length should correspond to the focal length of the X-ray grid, but it is difficult to make it due to the difference in the position and location of the shooting in actual work. The two are mutually opposing.
At this time, a range value should be specified, and the change range of the focal length in the specified range cannot be greater than or less than 25% of the focal length, or the pass rate of the original emission line at the edge of the effective area of the X-ray grid cannot be low, This is the limit value at 40%.
