Today, the editor will explain to you the precautions of the x ray bucky grid:
X ray bucky grids need to be noted during photography: the focus of the X-ray tube needs to coincide with the convergence line to make the radiation direction of the original emission line consistent with the direction of the lead strip, so as to pass the x ray bucky grid. The focal point and the convergence line of the x ray bucky grid are not in a state of coincidence, or the x ray bucky grid is placed within the specified focal length range, and excessive loss of the original emission line will occur. The greater the deviation, the greater the difference between the focal length and the focal length, and the greater the loss of the original emission line. Note for the grid: also need 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, and the focal length should correspond to the focal length of the x ray bucky grid.
The above are the precautions for the grid, you should understand it here.
