摘要
在传统超声图像重建的线性插值方法的基础上,提出了对非线性插值的研究,并将其运用到显示超声图像的模型中.先给出了两类非线性插值(三次多项式插值和自然样条插值)的基本原理,其次针对已存在的B型超声图像的数学模型,简化插值公式,最后给出了非线性插值与线性插值(R Theta)的对比结果,从而给出结论.
Traditionally, ultrasound images are reconstructed by one of linear interpolation methods.Some nonlinear interpolation methods are disussed.The application to one of ultrasound images displaying model is also proposed.At first,Two types of nonlinear interpolation algorithm (3 order polynomial interpolation and natural spline interpolation) is given. Then,the algorithm is simplified so that they can be used in real math model of ultrasound B scan images. At last,the result of nonlinear and linear interpolation algorithms (RTheta linear algorithm) are compared,and some possible conclusions are drawn.
