[0046] This embodiment provides a plane ultrasonic (hereinafter referred to as plane wave) imaging processing method based on virtual multi-angle compounding at the receiving end. figure 1 Shown is a schematic flow chart of the plane wave imaging processing method. Such as figure 1 As shown, the plane wave imaging processing method includes the following steps:
[0047] Step S1, transmitting a single-angle plane wave at the transmitting end, and receiving the first echo data of the transmitted plane wave at the receiving end;
[0048] Step S2, performing virtual delay at different angles on the first echo data of the single-angle plane wave in step S1 at the receiving end to obtain second echo data of N receiving planes at different angles;
[0049] Step S3, performing beamforming on the second echo data of N receiving planes at different angles according to the delay superposition principle, to obtain images of receiving planes at different angles;
[0050] Step S4, superi...
