Abstract: The frame rate (the number of images displayed in one second) of current ultrasound imaging machines is about 30-100 fps, which is sufficient for most clinical applications, even echocardiography. However, high frame rate ultrasound imaging, so-called ultrafast ultrasound imaging, has recently been achieved with improvements of ultrasound hardware. One major advantage of ultrafast ultrasound imaging is that it converts the ultrasound image into a “high speed camera”, in which any movement of an object in the view of ultrasound…
