Description

In this paper we have represented an experimental thesis study of how it is realized quality control in radiology. This control will was done for determining functional condition of radiological apparatuses. Its main porpoise was patient protection from excess irradiation and films that can be read clearly with a very good quality. In this study were introduced measurements carried out in Radiological Department of ''Mother Theresa'' hospitality nr.5 and were discussed their results. Measurements realized were: i) Compliance of light batch with RX batch ii) tension tube iii) current tube iv) exposure time v) tube reproduction. As a measurement equipment was used a multimeter that measures at the same time four physical parameters like tension (kVp), exposure time (ms), current (mA) and RFE (relative exposure film). Referring to standards results were satisfactory. They were within allowed values. Batches compliance resulted within standards. By calculations there was a smaller deviation, less than 1.1 cm. When tension tube changed with some values, from calculations resulted that reading values were too close of what we needed (within standards). An accurate tension induces a very good radiological film contrast. For different currents and constant tension, the curve was a horizontal line. Measured tension never changed, even though we changed current values. When tube current was changed with some values, from calculations resulted that reading values were too close of those allowed. When time exposure was changed with some values, from measurements and calculations was shown that for very short time there was a small deviation from standards. With increasing time exposure accuracy becomes high. During measurement of tube reproduction, RFE value remained unchangeable. Standard deviation was zero. Proper recommendations are given like periodicity of controls and other suggestions. Controls described in this paper are predicted to be used from physicists for occasional controls and measurements following certain procedures.
