Embodiment 1
[0043] Such as figure 2 As shown, Embodiment 1 of the present invention proposes a focused acoustic array imaging method, comprising the following steps:
[0044] Step 1) using an acoustic array of M array elements, adopting a single array element to launch all array elements to collect all the echo data in the imaging area, which is recorded as full matrix data;
[0045] The values of the mth row and the nth column of the full matrix data are as follows: the mth array element is the transmitting array element, and the nth array element is all the echo data of the imaging area of the receiving array element.
[0046] Step 2) The imaging area is gridded according to a predetermined resolution, and the imaging area is obtained according to the propagation path calculated by the geometric relationship between each receiving array element and the transmitting array element when it is directly incident or the set relationship when passing through the medium refraction Each pixel...
