An Algorithm of Ultrasonic Elastography Singularity Correction

位移图成像是超声弹性成像算法中一个非常关键的步骤。目前对于弹性成像的研究大多关注在位移图的成像过程和成像速度,而对于位移图中常出现的奇异点等噪点的修复,一直提及较少。简单介绍弹性成像的基本原理,并重点针对位移图中出现的奇异点提出一种修正算法。该算法能有效地修复位移图中的奇异点,具有高效和针对性强的特点。作为一种后处理算法,该算法可以运用于不同的弹性成像算法中,具有较高的使用价值。

Displacement diagram is a key step in ultrasonic elastography imaging algorithm. Currently most of the research attention elastography imaging process in the displacement map and imaging speed, and for the displacement map singularities often occur, such as the noise of repair, has been mentioned less. Introduces the basic principles of elastography and focuses on displacement map singularities appear-ance, proposes a correction algorithm. The algorithm can effectively repair the singular point displacement map, with efficient and targeted characteristics. And as a post-processing algorithm, it can be applied to different elastography imaging algorithm, has a high value.
