| Abstract: | Computer tomography(CT)is one of the most commonly used medical diagnostic methods,and its radiation dose and image quality have always been topics of concern.The evolution and development of the five kinds of testing phantoms,namely conventional CT dose phantom,extended CT dose phantom,conventional image quality phantom,automatic tube current modulation phantom,and anthropomorphic phantom,were summarized and analyzed in this paper.This article may provide guidance for the development of new CT dose phantoms and image quality phantoms. |
