Why is it important to use a grid during x-ray imaging on thicker body parts?

Using a grid during x-ray imaging on thicker body parts is crucial for achieving better detailed images. Grids are designed to improve image quality by reducing the amount of scattered radiation that reaches the image receptor. When x-rays pass through thicker body parts, scattered radiation can increase, leading to decreased contrast and clarity in the resulting images. The grid acts as a filter, allowing only the primary, unscattered x-rays to reach the film or digital detector, which results in images that have improved detail and contrast. This is especially important in areas with high tissue density, where clarity and detail are essential for accurate diagnosis.
