Lung MR-Imaging is challenging due to low proton density in the lung. Ventilation can only be visualized directly using exogenous contras agents such as hyperpolarized noble gases or 19F-containing gasses as a “contrast agents”. This work proposes a multi-channel transmit and receive (TX/RX) radiofrequency (RF) coil that supports eight TX/RX channels (4 loop- and 4 dipole-elements) for 19F and 1H lung imaging at 7.0T using a pTX-array.
