N2 - We develop principal components analysis for the optimal SNR phased-array magnetic resonance (MR) image recombination. As shown in our analysis, we can achieve the best possible SNR in both weak-noise and noisy cases, without needing to estimate the coil sensitivities or to remove noise effects using polynomial fitting or filtering. We provide both analysis as well as reconstruction techniques. Our results shed light on the performance of the phased-array image combination and give new insight into good image formation schemes.
