Aims and objectives
CT examinations are the valuable diagnostic tools with the increasing role in medical practice.
Nowadays,
the number of the CT examinations performed and the associated exposure of patients seems to be the challenge from the radiation protection point of view.
In some countries,
the overall dose related to CT examinations makes major or even the largest share in the population dose arising from the sources of the artificial ionising radiation [1].
To keep the patients doses on the reasonable level two actions have been undertaken: first,
establishment of the quality control (QC) tests and the second,
establishment of the diagnostic reference levels (DRLs).
The QC tests are preformed to check the device itself and to ensure that the CT device is in a proper technical condition. As the patient dose is the combination of the chosen protocol and the personnel skills,
the resulted dose of those two factors is hard to predict.
While the results of QC tests vary slightly between the devices,
the protocols and staff skills may lead to substantial differences observed between the locations,
even dozens of times [2-6]. The results obtained during this survey may be useful for the calculation of the average dose to public in Poland due to CT exams and for the evaluation of the diagnostic reference levels.
To get the reliable information the questionnaire on the number of examinations and the doses was prepared and disseminated among all X-ray departments in Poland.
This survey was supported by the Polish National Consultant in Radiology.
