One dimensional phase unwrapping can be sensitive to noise or inhomogeneities in the phase data. Reliable analysis of 1D phase data however, often is a crucial pre-processing step for many image reconstruction algorithms (e.g.a EPI ghost correction, multi-echo field maps, ...). In our work we present a method that does not require phase unwrapping for fitting a known model to any measured 1D phase distribution. The only preliminary information required for the method to work is the function of the fit model for which the fit parameters are to be extracted from the phase data.
