Which is the main effect of grid cut-off in radiography?

The main effect of grid cut-off in radiography is underexposure of the image receptor. Grid cut-off occurs when X-rays are either completely absorbed or scattered by the grid lines instead of passing through to the image receptor. This happens when the X-ray beam is misaligned with the grid or if the grid is not appropriately positioned, leading to insufficient radiation reaching the receptor.

As a result, the final image will appear darker than intended due to the lower amount of radiation exposure, which reflects an underexposed image. Understanding grid cut-off is crucial for radiographers, as it can negatively impact the diagnostic quality of a radiographic image by not capturing the desired anatomical details. Proper alignment and understanding of grid usage can help minimize the incidence of grid cut-off and ensure better image quality.
