Non-invasive detection of unstable vessel plaque using ultrasonic velocity-change imaging

血管斑块脱离是一个严重的问题，它会导致脑梗死和心脏梗死。应用超声速度变化成像方法对颈动脉斑块进行组织表征。构建了血管幻象中富含脂质区域的超声速度变化图像。超声速度变化显像法可清晰显示血管幻象中富含脂质的区域。提出了心跳补偿方法，并将其应用于超声速度变化图像的构建。

The detachment of blood vessel plaque is serious problem because it leads to the brain infarction and the heart infarction. The ultrasonic velocity-change imaging method was applied to tissue characterization of carotid artery plaque. Ultrasonic velocity-change images of lipid-rich area in the blood vessel phantom are constructed. Lipid-rich areas in the blood vessel phantom were clearly displayed by using ultrasonic velocity-change imaging method. The compensation method for heart beat was developed and was applied to construct the ultrasonic velocity-change image.
