What is image noise in the radiograph?

Image noise in a radiograph refers to the random variations in pixel values that can obscure or distort the true representation of tissues or structures within the image. It can result from various factors, including electronic interference, patient movement, or insufficient radiation exposure. High levels of noise can reduce the clarity and diagnostic quality of the image, making it challenging for radiologists to identify abnormalities. Reducing noise enhances the visibility of important details in the radiograph.
