Abstract
Quality control measurements have been carried out on 29 mammographic units. It was found that a large percentage of users obtained Optical Densities outside the recommended values. Resolution under routine conditions was below the limit of 14 lp/mm in about 50% of the units. The skin entrance dose was in a few cases in excess of 10 micro Gray, but the mean value was well below this upper limit. Analysis of the results obtained has indicated that proper calibration of kilo voltage panel indications and automatic exposure control systems is of outmost importance and should be performed regularly. (authors). 11 refs, 2 figs 3 tabs.
