Abstract:
Whole-body PET/CT scanning is accompanied by substantial radiation dose in clinic. A large proportion of the radiation dose for examination obtained from whole-boby PET/CT is from CT scan. So how to control radiation dose without impairing CT image quality determined by the clinic is particularly important. Anthropomorphic phantom is the best choice for the study of radiation dose and image quality in PET/CT. The article reviews the meaning of anthropomorphic phantom and the study about PET/CT image quality and radiation dose with the phantom, Then analyzes the relationship between image quality of CT in PET/CT and radiation dose in the practical application.
