如果能够利用个体的头型来估计脑结构坐标，脑磁图和近红外光谱将是更理想的脑功能成像方法，特别是对于人类幼儿。首先，我们提出了一个算法来估计大脑坐标与学龄前儿童的头部表面形状。其次，我们研究了它的空间误差范围内使用留一法程序内的38个样本的儿童头部和大脑结构。在估计的和实际的脑坐标之间，头部表面的标志平均误差为13.6 +/- 5.3 mm，颅内结构的标志平均误差为18.5 +/- 12.4 mm。NeuroReport 23：299-303（C）2012年威科健康垂直酒吧Lippincott威廉姆斯&威尔金斯。
If the brain structural coordinates could be estimated using the individual head shape, magnetoencephalography and near-infrared spectroscopy would be more ideal brain functional imaging methods especially for young human children. First, we propose an algorithm to estimate brain coordinates with reference to the head surface shape in preschool children. Second, we examined its spatial error range using a leave-one-out procedure within 38 samples of child head and brain structures. The mean error of landmarks was 13.6 +/- 5.3 mm on the head surface and 18.5 +/- 12.4 mm in the intracranial structure between estimated and actual brain coordinates.
