Abstract
We describe a technique of brain surface matching of single-photon emission CT and MR images in human subjects and document the accuracy of this technique with the use of fiduciary markers. This mismatch averaged 4.3 mm as measured by the fiduciary markers and 2.1 mm as measured by the root mean square distance.
摘要
我们描述了一种在人类受试者中对单光子发射计算机断层扫描（SPECT）和磁共振成像（MR）图像进行脑表面匹配的技术，并通过使用基准标记来记录该技术的准确性。通过基准标记测量，这种不匹配平均为4.3毫米，通过均方根距离测量为2.1毫米。
