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.展开更多
