摘要
Shear- warp是基于物体空间扫描的一种体绘制技术 ,与传统的体绘制法相比 ,具有速度快、图像质量高的特点。本文介绍了 Shear- warp算法的原理 ,并将该算法应用到旋转扫描超声心脏图像插值结果的可视化 ,实现了心脏三维解剖结构的快速、准确重建。
Shear warp is a volume rendering technology based on object order. It has the characteristics of high speed and high image quality by comparison with the conventional visualization technology. The authors introduced the principle of this algorithm and applied it to the visualization of 3 D data obtained by interpolating rotary scanning echocardiogram. The 3 D reconstruction of the echocardiogram was efficiently completed with high image quality. This algorithm has a prospective application in medical image visualization.
