N2 - High temporal resolution, such unique property is a big advantage of ultrasonography for measurement of tissue dynamics. High frame rate ultrasound can increase the imaging frame rate from several tensof Hertz of conventional ultrasonography up to several thousand Hertz and, thus, significantly enhances the advantage of ultrasonography. We investigated appropriate transmit-receive conditions for B-mode and blood flow imaging of the carotid artery at a very high frame rate of over 3 kHz using a linear-array probe. Also, we have also realized high frame rate echocardiography using spherically diverging beams (frame rate: 316 Hz), whose image quality is very similar to conventional beamforming (frame rate: 39 Hz). Such methods would be useful for measurement of tissue dynamics.
