Embodiment Construction

[0028] Next, the technical solutions in the embodiments of the present invention will be described in the following examples, which will be apparent from the accompanying drawings, and Based on the embodiments in the present invention, all other embodiments obtained without creative labor are not made in the premise of creative labor.

[0029] See figure 1 It will be appreciated that the principle of ultrasonic full focus technology is figure 1 Indicated. The full focus imaging is to virtual focus on the echo data matrix captured by the full matrix, and the imaging post processing is implemented. Full matrix capture process: It is arranged in sequence to be: Array element 0, element matrix elements 1, ..., and element N-1. Initiation element 0, N-module receives the echo signal and stored as S 11 S 12 , ..., s 1N ; Excitation the changing element 1, N-module receives the echo signal and stored as S 21 S 22 , ..., s 2N According to such push until the N × N A sweep data is received...

Description

Technical field [0001] The present invention relates to the field of ultrasound detection, in particular, relating to a high frame rate ultrasound full focus imaging system based on FPGA implementation. Background technique [0002] Ultrasonic phase-controlled array detection technology is a common method in the field of industrial non-destructive detection. Since the phase-controlled array technology has the advantages of rapid, accurate and adaptability, it is widely used in actual ultrasound detection. Since the ultrasonic phase control array can only perform single-point real-time focus, imaging resolution and accuracy; in recent years, it has gradually been replaced by ultrasonic full focus technology, and ultrasonic full focus technology is a high-level ultrasonic imaging phase-controlled array technology. Collect the full-matrix echo data in any point in the measurement area and perform virtual focus, and can overcome the disadvantages of the phase-controlled array technol...
