Cooney, C. Davis, J.B.Y. Chua, W. van der Putten, J.F. Malone] Considerable time and effort is spent in diagnostic imaging departments selecting, monitoring and servicing equipment in order to produce the optimum radiograph. However, the contribution of the viewing conditions, especially viewing boxes, towards image quality is often overlooked. The Diagnostic Imaging Department alone, in this centre, has in excess of 240 viewing boxes. Radiographic viewing conditions can have a significant effect on the apparent density and contrast of an image. In 1990 an EC working document was published setting out quality criteria for diagnostic radiographic images. In particular, it specified a number of criteria which the viewing conditions must fulfil in order to achieve accurate reporting on clinical radiographs and proper assessment of image quality. On the basis of the report, a study was carried out on the standard of the viewing boxes in two hospitals. It was found that none of the viewing boxes studied fulfilled all the criteria and over 70% of them did not meet any of the criteria. An important procedural problem has been identified that may contribute to the above findings, i.e. the viewing boxes are supplied and installed as part of the 'building programme' rather than as part of the equipping programme in new hospital projects in this country. Finally, experimental work was carried out to determine a means of upgrading the equipment to conform to the available guidelines.
