摘　　要：医源性辐射越来越被关注,在不影响诊断效能前提下,尽可能降低辐射剂量已成为业界共识。CT低剂量技术相关研究已成为当前热点,笔者就低管电压、自动管电流调制技术及相关影响因素进行综述。More and more people pay attention to medical radiation,it has become a consensus in medical imaging to decrease radiation dose as low as reasonably achievable,meanwhile not to decrease diagnostic efficiency for disease.Now,the studies about technology of lower CT radiation dose is becoming a hot point,in this paper,the effects of low tube voltage,automatic tube current modulation and factors on it will be reviewed.

关 键 词：辐射 低剂量 低管电压 自动管电流
