Scattered radiation fog can be reduced through which of the following methods?

Using a grid effectively reduces scattered radiation fog, which is an important factor in enhancing image quality in radiographic examinations. Grids are devices placed between the patient and the image receptor to absorb scattered radiation that would otherwise degrade the image. When X-rays pass through the patient, they can scatter in various directions. A grid helps to selectively absorb these scattered photons while allowing the primary (non-scattered) X-rays to reach the image receptor. This results in a clearer, higher-contrast image, minimizing the unwanted fog created by scatter.

Other options may not directly resolve the issue of scattered radiation fog. Lowering kilovoltage can lead to increased scatter due to a higher number of interactions within the tissue, whereas increasing OID (Object-to-Image Distance) can actually increase scatter reaching the detector by allowing more scatter to escape the patient. This emphasizes the effectiveness of using a grid in managing scattered radiation and improving the overall quality of radiographic images.
