摘要
插值操作是B型超声数字图像显示前的一个重要环节。目前有很多成熟的插值算法,效果较好的有双线性插值算法,R-Theta是一种基于双线性插值算法的算法。传统的R-Theta插值的图像虽然比较逼真,但程序执行时间较长,不能满足B超仪实时性的要求。在原算法的基础上,给出了一种R-Theta算法的快速实现方式,从而使程序的运行时间大大缩短。
Interpolation operation plays an important role before B-mode ultrasound digital images display.At present,there are various mature interpolation algorithms,among which bilinear interpolation algorithm has a good effect.And R-Theta is an algorithm based on bilinear interpolation algorithm R-Theta interpolation images are lifelike,but the program execution time is longer,and it can not meet the B-meter real-time requirements.Therefore,based on the original algorithm,a R-Theta method of rapid implementations is given,which can make the running time shortened.
