The purpose of using grid technology in X-ray imaging is to reduce scatter radiation and improve image contrast. When X-rays pass through the patient's body, some of them can scatter due to interactions with tissues. This scattered radiation can create unwanted noise in the final image, obscuring details and reducing the overall quality.

Grids are made of alternating strips of lead and a material that is transparent to X-rays (like plastic or aluminum). They are placed between the patient and the X-ray film or detector. The lead strips absorb scatter radiation while allowing the primary X-rays, which contain useful diagnostic information, to pass through. This selective absorption helps enhance the contrast of the image by minimizing the amount of scatter that reaches the film or detector, leading to clearer images that facilitate better diagnostic interpretation.

In contrast, the other options do not capture the fundamental role of grid technology. Patient comfort, image processing speed, and radiation dose management are important aspects of X-ray imaging but are not directly related to the primary function of grids. Grids specifically address the quality of the image by focusing on reducing scatter, thereby enabling radiologists to make more accurate diagnoses.
