INVITED WHO and Rational Reduction of Patient Dose [Elektronische Daten] [G. Hanson (INVITED)] WHO activities aimed at reducing patient dose, while maintaining satisfactory image quality, include rational use of diagnostic imaging, effective choices for examinations, equipment design and specification, quality assurance, and guidance for regulatory authorities and radiological personnel. To assist its Member States in developing a rational policy concerning imaging services WHO provides guidance through publications, its network of Collaborating Centres, and its expert advisers. Because approximately 2/3 of the world's population lacked diagnostic imaging services, early in the 1960s WHO became concerned with basic radiology. After several unsuccessful approaches WHO concentrated on development of the Basic Radiological System (WHO-BRS). Following a workshop held in Neuherberg, Germany, a guide for Quality Assurance in Diagnostic Radiology was published by WHO in 1982. A similar guide for Quality Assurance in Nuclear Medicine was also published in 1982. In collaboration with other international organisations WHO is preparing revised editions of both the Basic Safety Standards for Radiation Protection, and the five-volume Manual on Radiation Protection in Hospitals and General Practice. Regarding future needs, within any health care system there is a spectrum of imaging requirements ranging from the most essential to the most complex. Issues to be resolved involve the clinical decision-making process through which diagnostic imaging examinations are produced and the optimum mixture of imaging modalities.
