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.
