In this work we have developed a simple method of estimation of a potential SNR gain, which can be obtained for a given coil and body configuration. Four and six laboratory bench Qs measurements had to be carried out to allow for SNR gain calculations of 77 K Cu and Cu/HTS coils, respectively. It was tested on a 3 T whole-body GE scanner using planar counter-rotating-currents (CRC) and twin-horseshoe (HS) coils (receive only) integrated with a G-10 liquid nitrogen cryostat. Cryogenic performance comparison of the CRC and HS coils were carried out using a 3.0 T GE whole-body scanner.
