| 中文摘要: |
| 肝脏在大血管搏动的激励下会产生运动,其运动情况可以反映肝脏硬化的程度。文章利用M型超声技术检测肝脏在这种激励下的运动信息,通过相关技术提取M型超声图像中肝脏的运动包络,并从中提取特性参数,用作肝硬化程度的诊断指标。 |
| 英文摘要: |
| The liver moves in respond to impulses arising from the main blood vessels. The hardness of the liver may be reflected by this kind of movement. M-mode ultrasound technique was used in this paper to detect the information of the liver's motion. A method was proposed to extract the motion envelope of the liver using the correlation technique. Several feature parameters were then obtained from the envelope as indexes of the extent of the liver's hardness. |
