Claim Text:
1. A non-transitory computer-readable storage medium storing computer executable instructions that when executed by a computer, control the computer in order to perform a method of reconstructing a magnetic resonance image, comprising: controlling a nuclear magnetic resonance (NMR) apparatus in order to selectively produce a gradient magnetic field, where the NMR apparatus is specifically an MRI apparatus; controlling, during an MRI image acquisition, the NMR apparatus with the computer in order to cause NMR to occur in a resonant species of an object that is within a pre-determined distance of a plurality of magnetic field monitoring (MFM) probes, the plurality of MFM probes being positioned in order to be affected by the produced gradient magnetic field, where the plurality of MFM probes, has at least 8 MFM probes that are positioned in either a cube arrangement or a spherical arrangement in order to cover two or more MRI slice planes controlling, during the MRI image acquisition, the NMR apparatus in order to acquire MFM signals from the plurality of at least 8 MFM probes while the gradient magnetic field is being produced, where acquiring the MFM signals comprises: controlling the NMR apparatus substantially simultaneously with the wireless transmission of the Amplitude and frequency division modulated MFM signals to the NMR apparatus, in order to acquire NMR signals from an object undergoing an MRI scan while the gradient magnetic field is being produced, where the NMR signals are then reconstructed into a magnetic resonance image; controlling the NMR apparatus with the computer in order to process the acquired NMR signals with the MFM signals, where processing the NMR signals includes reconstructing an MR image that is suitable for viewing from the MFM signals; and displaying the reconstructed MR image.
