What is considered an advantage of utilizing the air-gap technique in radiography?

Utilizing the air-gap technique in radiography offers the important advantage of less radiation exposure to the patient. This technique involves increasing the distance between the X-ray tube and the film or detector by using an air gap, which can significantly reduce the amount of scattered radiation that reaches the imaging receptor. Since scatter radiation contributes to the overall dose without enhancing image quality, minimizing it leads to a more focused X-ray beam that can improve patient safety by decreasing their exposure to radiation.

Moreover, when using the air-gap technique, the image quality may improve slightly due to decreased scatter, but the primary goal is to provide a safer environment for the patient. It is worth noting that while this technique can enhance image quality and some aspects of contrast, these are not the primary reasons for its use and benefit in terms of patient radiation dose is a more critical factor in radiographic practice.
