A field camera consisting of 16 proton based field probes is used to characterize the Parallel Acquisition Technique with Localised gradients (PatLoc) gradient coil. Higher order magnetic field monitoring is performed with a 16 channel proton field camera. The recorded field dynamics are used to test the linearity of the PatLoc gradient coil performance in combination with standard linear gradients and to measure the gradient impulse response functions of the five channel gradient system.
