As the number of CT examinations performed is continuously growing each year, radiation protection in the field of computed tomography deserves special attention from both radiologists (in the form of clinical justification of examinations) and radiological technologists (in the form of technical optimization of radiation dose). While performing CT examinations, radiological technologists could use a variety of optimization strategies for reducing the radiation dose. Therefore, the learning objectives are as follows: to acquaint the reader with the basic concepts and biological impact of radiation and...

Databases “Science Direct” and “PubMed.gov” were searched including the combination of terms "computed tomography", "radiation protection" and "dose optimization". We also used legal regulations of the Republic of Croatia and the ICRP recommendations related to the radiation dose limits.

The search returned a total of 4361 articles available by keywords. Due to the continuous development of technology in the field of CT, we focused on papers published from 2016 onwards and written in English language. The number of articles used in writing was limited to 21, while articles of older publication dates were used to list the original citation authors. From the point of view of a radiological technologist, the most important parameters of radiation dose reduction that we can (must) use in everyday...

Although the importance of following the ALARA principle may be inadvertently neglected in daily work, whether due to lack of equipment, inadequate working conditions or haste, we should keep in mind that radiologic technologists, as part of the radiology team on a monthly, annual or lifelong basis participate in conducting a significant number of CT examinations and thus greatly affect the average radiation dose of the population. As the computed tomography is a source of invaluable diagnostic information and the number of CT examinations performed...
