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.
