在这项工作中，我们提出了一种新的射频和梯度组装在9.4特斯拉189毫米磁铁的操作。设计该组件是为了实现基于质子观察碳编辑方法或梯度选择双量子相干的1H-NMR灌注研究。该探头组件的RF部分由分别在400和100 MHz下工作的改良Alderman-Grant线圈和鞍形线圈组成。这些线圈被主动屏蔽的Zgradient包围，这也允许使用基于梯度的水抑制，而无需碳选择。我们证明，这种探针可以用来实现梯度选择的双量子相干实验，导致高度的水抑制。
In this work, we present a new RF and gradient assembly for operation in a 9.4 Tesla 189 mm magnet. This assembly was designed in order to enable1H‐NMR perfusion studies that are based on proton‐observed carbon‐edited approaches or gradient selected double quantum coherence. The RF portion of this probe assembly is comprised of a modified Alderman‐Grant coil and a saddle coil operating at 400 and 100 MHz, respectively. These coils are surrounded by an actively shieldedZgradient, which also allows for the use of gradient‐based water suppression without the need for carbon selection. We demonstrate that this probe can be used to implement gradient selected double quantum coherence experiments resulting in a high degree of water suppression.
