Ultrafast Ultrasound: Potential Applications in Cardiac Anesthesia and Intensive Care

Figs 1A and B: (A)In conventional ultrasound, the structure is scanned line-by-line; (B) In ultrafast ultrasound, the structure is scanned by a single emission of plane wave.It can be combined with power Doppler imaging for imaging of blood flow.The use of power Doppler decreases the angle dependency and the high frame rate helps to filter out tissue movement.Ultrafast ultrasound can also be used to assess the transmission of shear waves arising from natural movement or induced acoustic stimuli.The tissue stiffness can be interpreted from the shear wave velocity
