Keywords: RF Arrays & Systems, Data Analysis, Receive Array SNRWe present a MATLAB based visualization toolbox for locating coil elements and evaluating SNR for flexible coil arrays. The greater variation in coil positioning creates challenges for SNR comparisons. By locating coils with coil sensitivity isocontours, the SNR of individual channels can be evaluated while the coil array is flexed. This is used to examine the repeatability of placement, and changes to coil coupling in the different placements. The coil locations can be validated using the SNR visualization displayed as slices, lines, and probe points. Expectations of the SNR field shape are used to further optimize coil locations.
