Since two years first phased array coils for human lung imaging with hyperpolarized 3He were presented. To understand and analyse the possibilities of phased array usage in lung imaging a 32channel phased array for 3He was designed and tested with several improved scan protocols to test out limitations of this technique. Compared to standard protocols high resolution 2D and 3D imaging was successfully realised as well as dynamic imaging with high temporal and spatial resolution. The results show up improved and new ways in functional lung imaging which can increase patient comfort as well as gain of information.
