Ultrasound images from human arteries obtained in vivo with an intravascular 30 MHz ultrasound imaging device show that blood echogenicity changes during the cardiac cycle. Quantitative measurements of blood echogenicity during the cardiac cycle suggest that these variations may be related to changes in the state of erythrocyte aggregation, which are induced by varying shear rate.
使用血管内30兆赫超声成像设备在体内获取的人体动脉超声图像显示，在心动周期中血液回声性会发生变化。对心动周期中血液回声性的定量测量表明，这些变化可能与由不同剪切速率诱导的红细胞聚集状态的改变有关。
