A system and method for quantifying opaque inhomogeneities within a fluid sample. Magnetic resonance signals of a first data set over k-space and magnetic resonance signals of subsequent reduced data sets over part of k-space are acquired, and data of the subsequent reduced data sets are completed with data of the first data set in order to obtain a full image of the scanned object. Each chip sub-module may be tested before being plugged into the MCM. The side shield overlaps the front portion of an eyeglass frame, sealing the side shield against the eyeglass frame and preventing the side shield from sliding backward.
