ALSO NUMBERED AS BS 7725: SECTION 2.4: 1995 Describes a method to check the constancy of the quality of images produced by hard copy cameras. Applies to hard copy cameras producing images on monochrome continuous tone material and comprising types of camera using a cathode ray tube, laser beam, or a thermoprinting system as used in diagnostic imaging systems. Also gives terminology, diagrams and annexes.
