ALSO NUMBERED AS BS 7725: SECTION 2.5: 1995 Defines the functional parameters which describe or affect the performance of image display devices used in diagnostic imaging systems. Also defines methods of checking that variations in measured quantities related to those parameters are within acceptable limits. Does not apply to video monitors used in indirect radioscopy systems. Does not deal with: optimisation of imaging performance; aspects of mechanical and electrical safety. Also gives definitions, diagrams and annexes.
