Abstract

The aim of this study was to undertake a comprehensive evaluation of selected mammography unit. The materials used mammography machine Philips, multi-electrometer, target and filter combinations W/Rh, Mo/Rh and Mo/Mo and Aluminum layers. The quality control assessment was performed on the selected machine. The assessment was done included kV accuracy and reproducibility and Half Value Layer measurement. The results obtained confirmed that the machine is workingcorrectly and was within acceptable performance criteria. The results of the physical parameters indicated a deviation of tube potential for the examined tube from the nominal values with the standard deviation (± 5%), except the few values exceeds this levels, and the conclusion is that some adjustments showed be done and the have value layer at the nominal tube potential (28kV) was in agreement with the published values.
