The primary purpose of using grids in radiography is to decrease scatter radiation. When x-rays pass through the body, some of the rays are scattered in different directions due to interactions with tissues. This scattered radiation can fog the image, reducing contrast and making it difficult to interpret.

Grids are designed with a series of thin lead strips that absorb the scattered radiation while allowing the primary x-ray beam to pass through. This selective absorption enhances the quality of the radiographic image by improving contrast, as the increased amount of primary radiation that reaches the film or detector results in a clearer and more precise representation of the structures being imaged.

The other options, while related to radiographic practices, do not accurately describe the primary function of grids. Focusing the x-ray beam is typically achieved through the use of collimators, increasing exposure time is not the role of grids and might inadvertently reduce image quality if not managed properly, and although grids can contribute to improved image resolution indirectly by reducing scatter, their main design intent is to mitigate scatter radiation. Therefore, the use of grids is essential for obtaining high-quality images in radiography.
