锥形束CT图像去噪与重建算法的研究进展
|
摘要
随着图像引导放疗技术(ImageGuidedRadiotherapy,IGRT)在临床应用中的不断推广,锥形束CT(Cone Beam CT,CBCT)以其开放式架构,可直接获得三维图像等优点,已成为目前IGRT开发和应用的热点技术之一。本文简单介绍了CBCT成像系统的组成与特点,重点分析比较了近年来常用的去噪与重建算法的具体原理及优缺点,并对其发展趋势做了总结与展望。
With the continuous promotion of image guided radiotherapy(IGRT) in the field of radiotherapy,cone beam CT(CBCT) is now becoming one of the most promising technology in IGRT application because of its open architecture and directly obtained three-dimensional images.This paper briefly describes the composition and characteristics of the CBCT imaging system,mainly compares the specific principle and advantages/disadvantages of the denoising and reconstruction algorithm,and prospects its future development.
