摘要

描述了一种双调谐单个核磁共振(NMR)探针的新方法，同时为单个输出提供两个共振。这两个频率都提供了高灵敏度，并且很容易通过特殊的非相互作用频率去耦电路进行调谐。双调谐表面线圈的/sup 1/H(质子)成像模式通过激活引脚二极管电路与全身圆极化发射谐振器主动解耦。图中显示了含有水和磷酸的幻影的结果

A low-lossy double tuned resonator for concurrent /sup 1/H and /sup 31/P nuclear magnetic resonance

A novel method for double tuning a single nuclear magnetic resonance (NMR) probe, providing two resonances to a single output, simultaneously is described. Both frequencies provide a high sensitivity and are easily tuned with special noninteracting frequency-decoupling circuits. The /sup 1/H (proton) imaging mode of the double-tuned surface coil is actively decoupled from the whole-body, circularly polarized transmit resonator by activating a pin diode circuit. Results for a phantom containing both water and phosphorus acid are shown.<>
