Abstract:
With the rapid increase of MRI systems in hospitals in China,national multi-sectoral strategies have been put forward to clarify requirements for improving image quality of MRI systems and preventing application risks in clinic.Quality control of MRI systems becomes an important task for regulators as well as hospital radiology departments.The tools used for quality control include imaging performance phantom and specialized function phantom,which can realize detection or calibration for parameters such as high contrast resolution,image uniformity and relaxation time.This article mainly reviews the research progress of the operation principles,common types and clinical applications for these two types of phantoms mentioned above.
