摘要

Computed Tomography(CT) is extensively adopted in diagnostic imaging world over due to various advantages over other imaging techniques. This eventually resulted in higher population doses. Oman is also not an exception to this. In 2007, there is a fifteen percentage increase in CT examinations in Ministry of Health hospitals alone than the previous year. To obtain good quality CT scans with optimal patient dose, a comprehensive radiation acceptance and quality assurance programme has to be in place for CT scanners. Here in this study validation of such a programme employed in Ministry of Health, Oman for CT scanners in various Ministry of Health hospitals is discussed. Though a large number of parameters were analysed for the study, we include a few from them - Computer Tomography Dose Index (CTDI), Scatter radiation levels, CT numbers, Noise, Slice thickness from four different vendors.
