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 ultrahigh‐field magnetic resonance microscopy. We show that due to the low‐loss ceramics used to fabricate the resonators, and a favorable 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 2 compared with a solenoid optimized for one sample.

使用用于 17.2 T MR 显微镜的耦合陶瓷谐振器对具有单个发射/接收通道的两个样品进行成像。

在本文中，我们讨论了使用耦合陶瓷谐振器和一个发射/接收通道在同一采集时间内对两个样品进行成像的可能性。我们在理论上和实验上比较了我们的陶瓷双谐振器探头与绕线螺线管探头的操作，后者是超高场磁共振显微镜中使用的标准探头。我们表明，由于用于制造谐振器的低损耗陶瓷，以及导电样品内电场的有利分布，包含两个样品的双探针实现了 SNR 增强接近平方根2 与针对一个样品优化的螺线管相比。
