Real-time shim adjustment substantially reduces spatiotemporal B field variation, opening the door to more robust imaging and spectroscopy investigations of the spinal cord. Magn Reson Med 80:935-946, 2018. © 2018 International Society for Magnetic Resonance in Medicine.

The lost field values near the edges of the brain can be recovered through an easily implemented adaptation to conventional SHARP.

Purpose: To design a phantom capable of mimicking human respiration to serve as a testing platform for correction of the static and time-evolving magnetic field distortions typically encountered in MRI of the spinal cord. Methods: An inflation system to mimic the air variation of the human lungs was constructed. The inflation system was linked to a phantom containing synthetic lungs and an ex vivo human spine. The relationship between air pressure and phantom lung volume was evaluated via imaging experiment. The geometric distortion (pseudo-displacement) caused by the B 0 inhomogeneities was measured on echo planar imaging slices for different air volumes.
