Phase-Cycled (PC) bSSFP imaging is useful for qualitative and quantitative studies of tissue. But the images generated should be properly combined when they are acquired with multiple receiver coils; in particular, phase information in the complex images must be preserved. We describe a straightforward yet optimal coil combination algorithm for PC-bSSFP applications, where the phase is preserved through relative phase alignment along the measurement dimension. The method is demonstrated with experimental results from phantom and volunteer scans.
