AbstractObjective: In order to reduce the effective dose level of the patients to explore the best scanning conditions, various factors affecting the level of PET/CT examination were analyzed. Methods: The effective doses of CT and pet were calculated respectively during PET/CT examination, Scanning parameters of CT and PET were optimized to reduce the effective dose of patients to a minimum while maintaining the image quality. Results: The tube voltage and tube current of CT, the injection dose during PET examination can affect the effective dose of the patients significantly. Conclusion According to different types of patients and diseases to develop personalized scanning program, the effective dose level of the patients can be significantly reduced.
