摘　　要：采用坐标变换和线性插值的方法,对由超声仪采集而来的二维小儿心脏超声切面图像进行重构,产生三维模型,并显示出在该模型中任意位置和角度的切面图像,对3种显示切面图像的方法在效果和时间复杂度上进行了比较,表明了这些方法在显示切面图像方面的可行性。With the methods of coordinate transformation and linear interpolation,a 3D model can be reconstructed by the 2D slices obtained from ultasound devices and images of slices at any position and any angle from this model can be gotten. And three methods of displaying slice images are compared on factors of quality and time. The result shows that the three methods are feasible.
