摘要
MRI对医学诊断有重要价值,而去噪是MR图像分析与诊断的基础问题之一。因此,探讨能消除MR图像噪声的方法具有重要的临床意义和应用价值。作者从空间域、变换域及多尺度分析等方面对MR图像去噪算法进行综述,分析和比较其性能,并对医学图像去噪领域的前景和趋势进行展望。
Magnetic resonance imaging （MRI） is of great importance in medical diagnosis, and denoise is one of the basic problems in MR image processing and analysis. Therefore, development of methods for eliminating image noise in MRI has important clinical significance and application value. In this paper, denoise in the space domain, transform domain and by multi-scale analysis and other aspects of MRI image denoising algorithms are reviewed, analyzed and their performances are compared. Finally, prospects and future trends for the field of medical image denoising are analyzed.
