Setting the phase of the virtual coil in the Direct Virtual Coil (DVC) reconstruction technique is both critical to achieving a high quality reconstruction and challenging, especially with high channel count arrays. In this work, a region growing approach to setting the virtual coil phase is described and evaluated in the context of the DVC technique. We demonstrate that the approach is able to generate sensible virtual coil phase even in challenging situations.
