阵列线圈成像在人体全身 MR 系统中的优势众所周知，并且已在许多应用和 MR 技术中获得相关性。在小动物研究领域，这个概念变得越来越重要。在这项工作中，提出了三种不同的相控阵线圈，用于对小鼠进行 MRI。为了在 300 MHz 下成像，引入了四通道仅接收相控阵线圈。工作频率为 750 MHz 的一个两通道和一个四通道发射/接收设置显示了 17.6 T 的阵列线圈成像的可行性。所有这些线圈都表现出出色的性能，并提供高质量的小鼠 MR 图像。版权所有 (C) 2007 John Wiley & Sons, Ltd.
The advantages of array coil imaging in human whole-body MR systems are well known and have gained relevance in many applications and MR techniques. In the field of small-animal studies, this concept has become increasingly important. In this work, three different phased-array coils for performing MRI on mice are presented. For imaging at 300 MHz, a four-channel receive-only phased-array coil is introduced. One two-channel and a four-channel transmit/receive setup operating at 750 MHz show the feasibility of array coil imaging at 17.6 T. All of these coils show excellent performance and deliver high-quality MR images of mice. Copyright (C) 2007 John Wiley & Sons, Ltd.
