Conclusion Phase-contrast MR imaging is proved to be an accurate and practical flow measurement technique in flow phantom study and can be used in quantitative study of blood flow clinically.

So it is one of the chief factors to set up measurement systems that can measure dielectric parameters of real tissues and equivalent phantom models, so as to carry through experimental studies.

Purpose To introduce a selfmade solid calibration phantom for bone mineral density(BMD)measurement with quantitative CT(QCT).
