Using the MRI system phantom we demonstrate the utility of the embedded MR-readable thermometer to measure and correct for temperature variations, demonstrate the use of the fiducial array to characterize scanner geometric distortions and the efficacy of software distortion corrections, and finally look at the effect of the electromagnetic properties of the phantom fill on quantitative measurements.
