Abstract
We previously described a technique for correcting patient-specific magnetic field inhomogeneity spatial distortion in magnetic resonance images (MRI), which was not applicable to patients fitted with MRI-compatible stereotactic fiducial frames. Here we describe an improvement to the technique that permits application for these patients. Measurements with a cadaver head show that this method achieves MRI stereotactic localization accuracy of 1 mm. J Image Guid Surg 1:151–157 (1995). © 1996 Wiley-Liss, Inc.
基于框架立体定向手术的磁共振图像畸变校正方法及初步结果
我们之前描述了一种校正磁共振图像(MRI)中患者特异性磁场不均匀性空间畸变的技术，该技术不适用于配备MRI兼容立体定向基准框架的患者。在这里，我们描述了一种改进的技术，允许这些患者的应用。对尸体头部的测量表明，该方法的MRI立体定向定位精度为1mm。[J]中华影像杂志(英文版);©1996 Wiley-Liss, Inc
