| Abstract: | This paper retrospects the level of CT technologies.CT technologies enter low dose imaging times based on CT developing history and current CT situations.ALARA principle is key standard for doctors using CT low dose technologies in routine clinical works.There are a lot of CT low dose imaging technologies,and how to grasp and use the technologies is a big challenge for radiological doctors.The author surgests doctors should have a very good continous study consciousness for the sake of grasping CT low dose imaging technologies. |
