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.
我们之前描述了一种校正磁共振成像（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。在此，我们描述了该技术的一种改进方法，使其能够应用于这些患者。对一具尸体头部的测量表明，该方法实现了1毫米的MRI立体定向定位精度。
