Abstract

A procedure which incorporates the aspects of both correction matrix and digital filtering to compensate for sensitivity fall-off of the surface coil has been applied to clinical imaging. In this method the surface coil profile is determined using the surface coil image and a crude body coil image. Our results indicate that the corrected surface coil image exhibits the homogeneity of the body coil image while essentially preserving the sensitivity of the surface coil image.

摘要

一种结合了校正矩阵和数字滤波两个方面以补偿表面线圈灵敏度下降的方法已应用于临床成像。在这种方法中,使用表面线圈图像和粗略的体线圈图像来确定表面线圈轮廓。我们的结果表明,校正后的表面线圈图像呈现出体线圈图像的均匀性,同时基本保留了表面线圈图像的灵敏度。
