Algorithm for estimation of brain structural location from head surface shape in young children

如果可以利用个体头部形状来估计大脑结构坐标，脑磁图将是更理想的脑功能成像方法，特别是对于年幼的人类儿童。我们提出了一种参考学龄前儿童头部表面形状来估计大脑坐标的算法。在估计的和实际的脑坐标之间，地标在头部表面的平均误差为13.6±5.3 mm，在颅内结构上的平均误差为18.5±12.4 mm。

If the brain structural coordinates could be estimated using the individual head shape, magnetoencephalography would be more ideal brain functional imaging methods especially for young human children. We propose an algorithm to estimate brain coordinates with reference to the head surface shape in preschool children. 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.
