摘要 介绍了在二维超声眼球切片中定位信息的提取方法,根据眼球切片间的相关性调整切片间的相对位置,并且采用基于弹性匹配插值算法在切片间进行匹配插值,然后采用基于体数据重建的光线投影算法进行三维重建。 This paper describes an algorithm of extracting location information in 2D eyeball ultrasound slices. The relative position of eyeball slices is adjusted based on the correlation between the slices. Some middle slices are added with elastic matching-based interpolation algorithm. Then ray-casting algorithm for volume rendering is used to reconstruct 3D image of the eyeball.
