Measurement of cardiovascular dynamics is valuable for diagnosis of the cardiovascular system. High frame rate ultrasound, which was introduced in the 1980s [1], is a promising technique for such purposes. This technique uses unfocused transmit beams and creates multiple focused receiving beams in each transmission. High frame rate ultrasound was first applied to the measurement of the displacement distribution in tissue induced by acoustic radiation force for assessment of viscoelasticity [2]. Recently, we have shown that high frame rate ultrasound is also useful for B-mode, tissue strain, and blood flow imaging [3]. Currently, various methods based on high frame rate ultrasound have been developed for measurement of cardiovascular dynamics [4-8]. In this presentation, recent development in high frame rate ultrasound and its application to measurement of cardiovascular dynamics are shown.
