摘要X射线的影像学检查是现代化精准医疗中的重要环节,在诊治疾病和判断疾病转归及手术方案制定中发挥着不可替代的作用.随着数字X射线和CT检查的广泛应用,重复的和过度的X射线检查时有发生,使受检者接受了过多的或额外辐射剂量,引起辐射损伤.如何优化辐射剂量,达到既满足疾病的诊断,又能降低受检者的辐射损伤,是研究者和设备研发者关注的重要课题.以致X射线的辐射损伤引起了政府、社会、受检者和X射线检查工作者的高度关注.本文探讨了降低辐射剂量的方法,评述其进展.

abstractsX-ray examination is an important part of modern precision medicine,and plays an irreplaceable role in the diagnosis and evaluation of disease outcomes as well as the surgical planning.With the widespread use of digital radiology and CT examinations,repeated and excessive X-ray examinations occur that cause the subject to receive excessive or additional radiation doses which cause radiation damage.How to optimize the radiation dose to meet the diagnosis of the disease and reduce the radiation damage of the subject is an important topic for researchers and equipment developers.As a result,X-ray radiation damage has attracted the attention of governments,society,subjects and X-ray inspection workers.This article explores ways to reduce radiation dose and reviews its progress.
