Abstract
Digital imaging began in the mid-1960s as a by-product of space missions. Cameras in the unmanned spacecrafts provided distorted and lopsided images of the moon's surface and a need was felt to get a clearer view. NASA (The National Aeronautics and Space Administration) then developed digital technology whereby analogue signals were converted into digital signals, which when fed into a computer, produced enhanced images that could be more meaningfully interpreted.[1] In medicine, this technology has been used for computed tomography, ultrasound imaging and magnetic resonance imaging, which would not have been possible with conventional imaging using film-based photography.
