摘　　要：在用不同方法实现了医学图像体数据平面重建功能的基础上,对三个成像平面中鼠标确定的控制点采用B-Spline的方法拟合曲线,并根据任意设置的采样步长,以平面的方式显示曲线确定的面对应的医学图像体数据,从而实现了医学图像体数据的高精度曲面重建,成功的避免了用线段近似曲线所带来的误差。通过实验对比,择优选取帧速率较高的方法,实现了基于普通PC平台的MPR软件组件。Multi-planar reformation （MPR） of medical imaging volume data was realized in several different ways. Based on this, B-Spline was used to produce a curve with control points input by mouse in three views and the medical imaging volume data determined by the curve according to the sample step specified at will was shown. Medical imaging volume data curved planar reformation （CPR） of high-precision was realized avoiding errors brought by simulating curves using pieces of lines. A better method was chosen after some experiments. MPR modules based on common PC platform were realized.
