A radiograph of an axiolateral (inferosuperior)projection reveals that there is an excessive amount of grid lines present.A 6:1 linear grid was used.Which of the following points will correct this problem on the repeat exposure?

Question

Quizplus · Accepted Answer

Excessive grid lines can occur if the image receptor is not aligned parallel to the grid lines. Keeping the image receptor parallel to the femoral neck and perpendicular to CR will ensure that the grid lines are not visible on the resultant image. Using a screen instead of a grid or decreasing the SID will not correct this problem. Keeping the image receptor perpendicular to the femoral neck will also not correct the problem because it does not address the issue of grid line visibility.
