摘要 介绍了保边界的有偏距离加权同心插值法 ,在对三维超声心动图进行插值处理时 ,把三维规则不均匀的数据场变为规则均匀的数据场 .实验证明 ,该方法克服了常用的同心插值法的低通滤波特性带来的图像边缘模糊效应 ,其计算简单、运算速度快 ,为实现快速三维重建提供了必备条件 . A warped distance concentric interpolation method for three-dimensional echocardiographic images was presented. This method can interpolate unequally distributed dataset to equally distributed dataset for afterwards 3D rendering. This method not only preserves image edge but also reduces computational costs.
