title: Quality control and patient doses in X-ray computed tomography.
abstract: Results of quality control (QC) tests for a period of over a year and patient doses were analysed for several computed tomography units in our centre. The results of the QC tests were generally within limits for all of the examined scanners, proving good and stable performance of the systems. The tests were not helpful in predicting breakdowns of the systems such as tube failure. The doses for the same anatomical areas differed between scanners and in some cases exceeded the diagnostic reference levels (DRLs). DRLs are defined for typical diagnostic examinations performed in general hospitals and are not directly applicable to the examinations performed in the oncological centre.
