Abstract

Prioritizing signal fidelity for PET and MR, we simulated, built, and tested a wide-bore 1.5T body coil with a concentric ring of novel PET shields. With such an approach, the inherent reduced transmit efficiency can be compensated for by applying more power. Through B1+ measurements in phantoms and in the head, we validate that dual RF power amplifiers meet the power requirements.
