The first steps in cardiac/body imaging at 7T have been reported. One of the challenges is a suitable TX coil concept, which adresses the RF problems (B1 homogeneity, SAR) of body imaging at 300MHz. Traditional bodycoils seem not to be the right way, a coil array enabling TX SENSE and B1 shimming seems to be more promising. We describe a 8-element TX/RX loop coil array with adjustable capacitive decoupling. A prototype has been realised and tested. First imaging results in cardiac imaging are shown.
