At first, the bony landmarks of the base cranium were used to estimate the layer images.
首先以颅底骨性标志作为估计图像的层次。
We input the MRI data to the medical image software and use 3d concept to measure several bony landmarks to find the relationship of those bony landmarks.
运用医学影像软体进行测量，以三维的观念测量各个参考点，并找出参考轴之间的关系与各参考点到关节面的距离，以建立国人膝关节参考点资料库。
The distances between the bony landmarks and joint line are also measured. The results of this study suggest that 3D conceptual measurement can reduce the errors from 2D images measurement.
研究结果显示，本研究突破以往用二维影像的测量来代表三维空间的距离及角度，避免以往因单张影像测量所造成的误差。
