| Research Abstract |
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.
