When using linear grids, what is the outcome of angling the tube?

Angling the x-ray tube when using linear grids typically results in no grid cut-off, provided that the tube is angled along the direction of the grid lines. Linear grids are designed to absorb scatter radiation while allowing primary radiation to pass through. When the tube is angled in the direction of the grid lines, the alignment with the grid is maintained, which enables the majority of the primary radiation to still reach the image receptor.

If the tube were angled against the grid lines, then grid cut-off could occur, which would result in a loss of image density or brightness and potentially impact image quality. However, as long as the direction of the tube angle is consistent with the orientation of the grid, it does not result in grid cut-off, thereby allowing for effective imaging without significant degradation of the image.
