Abstract:
Objective To design a test phantom for clinical routine quality control of magnetic resonance imaging (MRI).Methods The commonly used phantom such as Magphan SMR170 and Victoreen 76-903 were used for experiments with the same parameters,and the test data of all the modules were compared.The advantages and disadvantages of all the modules were analyzed,and an optimization scheme was proposed accordingly.Results The phantom could be applied to the detection of high-image-quality MRI machine,and solved the problems in positioning,size matching and etc.Conclusion The new phantom meets the demand of magnetic resonance imaging clinical routine testing,and provides a certain reference for phantom optimization design.
