A tailored receive-only coil for cardiac imaging has been designed. The coil consists of two overlapping coil elements and can be used either as a quadrature surface coil or as a phased-array coil. Through phantom experiments and images of the heart, the authors have shown that the improved cardiac coil provided a signal-to-noise ratio 1.6 times higher than a conventional quadrature spine coil, 1.4 times higher than that of a single coil (having the same shape and total dimension), and three times higher than the body coil at the depth of the posterior wall of the heart. The authors have also shown that the cardiac coil improved image quality everywhere in the heart. This coil will enhance routine clinical cardiac studies as well as other examinations such as myocardial perfusion, wall motion, and coronary artery imaging.
已设计出一种用于心脏成像的定制式纯接收线圈。该线圈由两个重叠的线圈元件组成，既可用作正交表面线圈，也可用作相控阵线圈。通过模型实验和心脏成像，作者表明，改进后的心脏线圈的信噪比在心脏后壁深度处比传统正交脊柱线圈高1.6倍，比单个线圈（形状和总尺寸相同）高1.4倍，比体线圈高3倍。作者还表明，心脏线圈在心脏各处都改善了图像质量。这种线圈将提升常规临床心脏研究以及其他检查，如心肌灌注、壁运动和冠状动脉成像。
