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.
