An MRI system phantom has been developed through collaboration between the ISMRM ad-hoc committee on Standards for Quantitative Magnetic Resonance and the National institute of Standards and Technology (NIST). This will be the first system phantom with SI-traceable components and the first to be monitored by NIST for stability and accuracy. The system phantom consists of the following elements: fiducial , T1, T2, proton density arrays; resolution, slice profile, and SNR insets. The system phantom is designed to assess scanner performance and quantitative mapping protocols and to easily compare performance with other scanners across the world. The system phantom has been imaged extensively at Mass General Hospital and M D Anderson Cancer Center in a variety of 1.5 and 3T scanners.
