| Abstract: | The frequency of CT examinations is increasing in the world and CT radiation dose has been being paid attention to in the public and scientific circle. Many technologies and methods allow an increase in the dose efficiency without the risk of inferior image quality, thus the radiation dose to patients to be reduced. This paper discusses briefly the principles, clinical use and limitations of the technologies and methods. |
