1. A method for spatially resolved determination of at least one magnetic resonance parameter that influences a magnetic resonance signal detected in acquisition of magnetic resonance data from a region of an examination subject, comprising: providing a first complex image data set to a processor that were acquired from an imaged volume of an examination subject with an echo imaging sequence during a first echo time, said first complex image data comprising at least one first image data set acquired with a first acquisition coil of a data acquisition unit in which said echo imaging sequence was implemented, and a second image data set acquired with a second acquisition coil of said data acquisition unit; providing a second complex image data set to said processor that were acquired from said imaged volume of said examination subject with said echo imaging sequence during a second echo time, said second complex image data comprising at least one third image data set acquired with said first acquisition coil and a fourth image data set acquired with said second acquisition coil; said first, second, third and fourth image data sets each comprising complex image points that respectively correspond with each other from data set-to-data set with respect to said imaged volume of the examination subject; in said processor, determining a magnetic resonance parameter for at least a portion of said image points of said first, second, third and fourth image data sets by determining, for each of said image points, a first image point vector for said first echo time from said first complex image data that comprises corresponding image points of said first image data set and said second image data set, and determining a second image point vector for said second echo time from said second complex image data, that comprises corresponding image points of said third image data set and said fourth image data set, and combining said first and second image point vectors to produce a vector combination for which echo time-independent phase portions or echo time-independent magnitude portions in the first and second complex image data set are compensated, and determining for each image point, at least one magnetic resonance parameter from said vector combination; and making the respective magnetic resonance parameters for the respective image points available at an output of said processor in a form for use in reconstructing an image from said image points.
