Diagnostic radiology better images--lower dose compromise or correlation? A European strategy with historical...

Quality Criteria for diagnostic radiographic images include the definition of necessary image details, performance of the imaging system and appropriate choice of radiographic parameters. Actions have established a framework for the optimisation of these three groups of Quality Criteria. Their evolution, practice and efficacy will be demonstrated for conventional and digital radiology. The link between the Quality Criteria and exposure of the patient and staff will be discussed. The historical follow up of these aspects will appreciate the efforts done all over Europe since the twenties and will reveal the potential for continuously optimising diagnostic radiology in many respects: in day-to-day practice, new technical design and radiological concepts.
