摘    要:由于超声成像机制使医学超声图像中存在着大量的斑点噪声,这些斑点噪声大大降低了图像的清晰度和质量,给超声诊断带来很大的困难。针对医学超声图像的斑点噪声去噪问题,提出了一种基于帧相关处理、ROF分解和自适应小波阈值的去噪方法,能够在抑制超声图像斑点噪声的同时,尽可能地保留甚至增强图像的细节信息,大大提高图像质量,取得了很好的效果。

关 键 词:斑点噪声  帧相关  全局相位相干性  ROF模型  自适应小波阈值

Abstract:There are always lots of speckle noises in medical ultrasonic images because of the imaging mechanism.These speckle noises significantly reduce the clarity of the image and as a result,cause great difficulties in ultrasound diagnosis.To solve this problem,this paper presents a new de-noising method for medical ultrasonic image based on ROF model and adaptive wavelet threshold de-noising method.In addition to inhibiting the speckle noises in the medical ultrasonic image,this method can retain and even enhance the image detail information as much as possible.
Keywords:speckle noise  frame correlation  Global Phase Coherence(GPC)  ROF model  adaptive wavelet threshold
