An automated method for tissue phase and susceptibility estimation from multichannel data is proposed. Using ESPIRiT with virtual body coil calibration on multichannel data, phase-sensitive coil combination is achieved without an additional reference acquisition. This is shown to perform similarly to SNR-optimal Roemer combination that requires additional reference body and head coil acquisitions. Estimation of the tissue phase from the combined data is posed as a regularized inverse problem using the spherical mean value property. The extension of the technique to single-step Quantitative Susceptibility Mapping is also demonstrated on 2D, 3D and Simultaneous MultiSlice data.
