High temporal resolution is a big advantage of ultrasonography for measurement of tissue dynamics. High frame rate (HFR) ultrasound can increase the imaging frame rate from several tens of Hertz of conventional ultrasonography up to several thousand Hertz and, thus, significantly enhances the advantage of ultrasonography. We realized HFR B-mode and blood flow imaging of the carotid artery at a very HFR of over 3 kHz using a linear-array probe. Also, we have also realized HFR echocardiography using spherically diverging beams (Fig. (a), 316 Hz), whose image quality is very similar to conventional beamforming (Fig. (b), 39 Hz). Such methods would be useful for measurement of tissue dynamics.
