Grid lines can occur due to improper alignment of the grid with the CR and image receptor. Keeping the image receptor and grid parallel to the femoral neck and perpendicular to the CR will correct this problem. Using a screen rather than a grid or decreasing the SID will not correct the issue with grid lines. Keeping the image receptor and grid perpendicular to the femoral neck can also cause grid lines.
