We propose a simple, SNR optimal method for coil
sensitivity estimation and adaptive combination suitable
for applications in which complex valued images are
required. The proposed method enforces smoothness in
both the magnitude and phase of the estimated coil
sensitivities and overcomes the limitations inherent in
previous methods. It has a very fast implementation and
can be easily incorporated into a reconstruction
pipeline. We demonstrate how this approach can mitigate
the problems with phase. It is likely to be useful in
applications such as susceptibility weighted imaging,
complex interpolation, complex motion correction, and
referenceless thermometry.
