数字人脑空间坐标转换方法

A method of spatial coordinates conversion in the digital human brain

目的介绍一种使用Excel软件实现数字人脑空间坐标转换的方法。方法首先在头部数据集中建立初始坐标系,然后通过坐标系的1次平移和坐标轴的3次旋转,建立人脑标准空间坐标系。结果建立了由初始坐标系到标准坐标系坐标转换的数据表。结论通过坐标转换,能够实现数字人脑坐标系统的标准化,为建立中国数字人脑模型提供支持。

Objective To describe a spatial coordinates conversion method for serial anatomical cross-sectional images of the human brain using the software, Excel 2003. Methods Initialization reference frame was established in serial anatomical cross-sectional images of the human brain. Then, a standard spatial coordinates was set up by one time horizontal moving and 3 times rotations of the reference frame. Results A datasheet about coordinates conversion from initialization reference frame to standard spatial coordinates was established. Conclusion Standard spatial coordinates was established in the digital human brain after coordinates conversion. It will be helpful to build Chinese digital brain model.
