A large aperture row column addressed probe for < i > in vivo < /i > 4D ultrafast doppler ultrasound imaging.

In this study, we designed and built a new Row and Column Adressed (RCA) probe dedicated to vascular imaging and investigated it with a specific Orthogonal Plane Wave (OPW) compounding strategy (Flesch et al., 2017). Using this prototype, 4D ultrafast Power Doppler imaging of a large volume of 25.6×25.6 mm² up to 40 mm depth is demonstrated in vitro on flow phantoms and vivo on the carotid artery of a healthy volunteer at a volume rate of 834 Hz.
