| Zusammenfassung | In this work a local four-channel transmit/receive RF coil dedicated for cardiac MR at 3T is compared to a conventional built-in body RF coil in conjunction with a four-channel receive-only RF coil. SAR and B1+ simulations of both configurations are shown. The invivo efficiency performance of both coils in respect to B1+/sqrt(SAR) is demonstrated in 12 healthy subjects. The efficiency surplus of the local RF coil was used to increase the applicable flip angle FASSFP of a standard high resolution 2D SSFP protocol or to shorten the used repetition time TRSSFP by 54%. |
