Problems solved by technology

Two defect imaging images can be obtained in real time during scanning, but since these two detection imaging technologies are used for scanning at the same time, the imaging frame rate of the entire system will be greatly reduced, and it is difficult to meet the real-time requirements of practical applications

Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] It should be noted that the all-focus imaging technology is realized by performing virtual focus imaging on the full-matrix data matrix. Full matrix data generation process: Suppose the probe has N array elements, which are arranged in sequence: array element 1, array element 2,..., array element N. Excite array element 1, N array elements receive echo signals and store them as S 11 , S 12 ,...,S 1N ; Excite array element 2, N array elements receive echo si...

Abstract

The invention provides a full-focusing and phased array double-scanning imaging method. When phased array and full-focusing double-scanning imaging is carried out, transmitting and receiving module control and focusing imaging processing of a phased array are simultaneously carried out in parallel in a full-focusing imaging time period. On one hand, mutual interference of the two modes is avoided,and it is guaranteed that the two imaging modes can work normally; and on the other hand, the imaging frame rate of the whole system is effectively increased, and therefore the real-time requirementin practical application is met.

Description

technical field [0001] The invention relates to the technical field of ultrasonic detection, in particular to an all-focus and phased-array dual-scan imaging method. Background technique [0002] Ultrasonic testing technology is a common method in the field of industrial nondestructive testing, and it is widely used in actual ultrasonic testing. Ultrasonic phased array detection and imaging technology is composed of multiple A-scan data. In different A-scan data processing, the A-scan ultrasonic sound is realized by controlling the transmission delay and reception delay of the pulse signal of each array element. Gathering and deflection of the beam, multiple A-scan data compose a frame of B-scan or C-scan image. Ultrasonic phased array detection imaging technology has the advantages of fast, accurate and strong adaptability, and the obtained image frame rate is relatively high. [0003] However, the ultrasonic phased array can only perform single-point focused scanning det...
