IEC 61223-2-9 Ed. 1.0 en:1999

Applies to those components of X-ray equipment which a) generate, influence the propagation of, and detect X-radiation, and b) process, present and store diagnostic X-ray images in radiological installations with diagnostic X-ray systems for indirect radioscopy and indirect radiography which use X-ray image intensifiers in conjunction with analogue and/or digital storage systems: - closed-circuit television display system - cut films cameras - cine cameras. This standard defines - the essential parameters which describe or affect the performance of the above components of X-ray equipment, and - methods of checking that variations in measured quantities related to those parameters are within acceptable limits, in order to maintain adequate standards of imaging whilst reducing unnecessary irradiation of the patient.
