Sparse total-focusing imaging of ultrasonic array sensor at the interface under an effective aperture

Total-focusing imaging based on full-matrix data, which makes the synthesis of sound waves at the focus point, has been widely used and shown to improve imaging resolution effectively. In traditional total-focusing imaging, it is considered that the echo signals received by all transmit–receive pair...
