Multi-element coil arrays are commonly used in magnetic
resonance imaging (MRI) for parallel imaging. However,
how to combine the magnetic resonance spectroscopy (MRS)
signal from a multi-element receiving coil array has
been much less studied than imaging. In this study, we
proposed a new method for theoretical optimal
combination no matter the noise is correlated or
uncorrelated among different coil elements. The
validation experiments were performed with different
voxel locations/sizes on a 3T MRI scanner with an
8-element head coil. The results verified the superior
performance of the proposed method compared with the
recently published and other routine combination
methods.
