A Comparison of Methods for Reducing the Number of Channels for SENSE

When combining a large array of coils so that it can be used on a system with a small number of receiver channels, two possible methods that might be used are to combine the array so that each channel is optimized to give the optimal SNR at a different point in the image, or to combine the array so that each channel is optimized to yield the optimal SNR over different regions of the image. These two methods are compared for SENSE imaging when a sixty-four element linear array is reduced to eight or sixteen channels.
