The issues of dose load control on patients caused by X-ray computed tomography (CT) are considered. It was found that in many countries of the world the prevalence of modern technologies of CT diagnostics is growing, however they are the ones that cause the greatest radiation exposure on the patient. In order to monitor the collective dose of CT scans within the state in developed countries a careful collection of statistics on CT studies is carried out. In Ukraine systematic monitoring of the

A promising solution to this problem is to create a national database of statistics of CT diagnostics. The analysis of data of the All-Ukrainian audit of CT on the number of CT systems in the country as of 2019 is carried out. Based on the obtained data the comparison was made between the data of the State Inspectorate for Nuclear Regulation of Ukraine (SINR) and the Ministry of Healthcare of Ukraine regarding the use of CT in the country. Significant differences in the number of CT systems have been identified, which indicates the absence of unified approaches to the accounting and monitoring of CT in Ukraine. A typical procedure for monitoring dose levels of irradiation during basic x-ray studies is considered. The main factors of the formation of the dose index for interventional and spiral CT are revealed. The possibilities of reducing the dose load on the patient due to a change in the multispiral CT scan modes are considered. To obtain reference dose index values for spiral CT, a dosimetric x-ray anthropomorphic phantom was scanned. The results can be used in the processing of CT audit data, for which a questionnaire form is proposed that contains the parameters of the CT study protocol and the results of measurements and calculations with the aim of further systematic assessment of the collective dose for CT in Ukraine.
