A prototype cardiac phased array receiver coil was constructed that comprised a cylindrical array and a separate planar array. Both arrays had two coil loops with the same coil dimensions. Data acquisition with the cylindrical array placed on the human chest, and the planar array placed under the back, yielded an overall enhancement of the signal-to-noise ratio (SNR) over the entire heart by a factor of 1.1-2.85 over a commercially available flexible coil and a commercially available four-loop planar phased array coil. This improvement in SNR can be exploited in cardiac imaging to increase the spatial resolution and reduce the image acquisition time.
构建了一种原型心脏相控阵接收线圈，它由一个圆柱形阵列和一个单独的平面阵列组成。两个阵列都有两个线圈环，且线圈尺寸相同。将圆柱形阵列置于人体胸部，平面阵列置于背部下方进行数据采集，与市售柔性线圈和市售四回路平面相控阵线圈相比，整个心脏的信噪比（SNR）整体提高了1.1至2.85倍。SNR的这种改善可用于心脏成像，以提高空间分辨率并缩短图像采集时间。
