The use of focused x ray grid

Cutting effect often occurs when using focused x ray grid. Therefore, attention should be paid to the use of focused x ray grid:
(1) focused x ray grid deletion can not be reversed.
(2) the X-ray centerline should be aligned with the focused x ray grid to delete the center line, and the deviation should not exceed 3CM.
(3) the X-ray centerline should be perpendicular to the focused x ray grid.
(4) when the X-ray tube is tilted, the inclination direction can only be parallel to the direction of the lead bar.
(5) when using the focused x ray grid, the distance between focus and x ray grid should be within the allowable concentration range.
