In an analog x-ray, a light sensitive film is exposed to the X-rays and followed by this, the film is developed. The digital X-ray has modernized this system and uses a digital detector system instead of the usual photographic light-sensitive film used in analog X-rays. So during the Xray session, the X-rays are directed to a particular part of the body so other parts of the body are not exposed to any radiation.
The digital detector system on opposite sides captures the incoming X-rays which varies in strength and converts them into electrical signals which are then shown on the computer. because there is no time needed for film development The X-ray images can immediately be collected after the exam a compared t the traditional system.
