Abstract
In this paper we address the possibility to perform imaging of two samples within the same acquisition time using coupled ceramic resonators and one transmit/receive channel. We theoretically and experimentally compare the operation of our ceramic dual-resonator probe with a wire-wound solenoid probe which is the standard probe used in ultra high-field Magnetic Resonance Microscopy (MRM). We show that due to the low-loss ceramics used to fabricate the resonators, and a favourable distribution of the electric field within the conducting sample, a dual probe, which contains two samples, achieves an SNR enhancement by a factor close to the square root of two
compared to a solenoid optimized for one sample.
