The advances of low radiation dose coronary computed tomography angiography imaging

Coronary computed tomography angiography(CCTA) has become a noninvasive method with high accuracy for evaluation of the coronary artery morphology, meanwhile, people have been paying more attention to the high radiation dose delivered during the imaging procedure. In recent years, it has been a hot research topic of keeping the radiation dose as low as possible with no sacrifice of the imaging quality. This article summarized and explored the advances of methods in reducing radiation dose for CCTA.
