Neofotistou, M. Molfetas, N. Panagiotakis] Four hundred tubes in 187 X ray diagnostic units were tested according to the protocol for the quality control of conventional X ray units issued by the Hellenic Association of Medical Physicists. The analysis of test results showed that 70% of diagnostic rooms were adequately shielded but only 30% had warning labels or signs. Of the generators assessed, 55% showed acceptable linearity, 65% had good kVp accuracy whereas 25% operated with single-phase waveform. Of the X ray tubes checked, 70% had adequate beam filtration, 40% had a focal spot size less than 1.3 mm and 75% had proper beam alignment. Eighty per cent of the standing buckies tested had FFD = 1 m. Of the fluoroscopic units assessed, 80% were equipped with image intensifier, 60% had a proper limit timer whereas in 25% beam limitation was performed automatically. Moreover, in 60% of the radiographs image quality could be improved by improving the working condition of film processors and intensifying screens. The results confirm the need for the propagation of Quality Assurance in Greece.
