What is the term for unwanted radiation exposure on the x-ray image due to scatter radiation?

The term for unwanted radiation exposure on the x-ray image due to scatter radiation is referred to as scatter radiation fog. This phenomenon occurs when x-rays are scattered off structures within the patient’s body or surrounding environment and result in additional exposure on the image. This scatter can obscure the desired anatomical details and contribute to a general haziness or fogging effect, which can degrade the overall quality of the radiographic image.

By understanding the concept of scatter radiation fog, radiologic technologists can take precautions to minimize this unwanted exposure, such as using appropriate shielding, optimizing collimation techniques, and employing imaging protocols that limit scatter. Recognizing the impact of scatter radiation is crucial for achieving high-quality diagnostic images while also ensuring patient safety.
