Problems solved by technology

[0004] But such demonstration test block and imaging process have the following defects: 1. The imaging speed of the demonstration process is slow, and the probe needs to be moved from the two directions of the length and width of the demonstration test block; 2. The depth of the specific character groove in the demonstration test block is fixed. value or a few limited specific values, the performance of the instrument ca...

Abstract

The invention relates to a design method of a verification test block suitable for plane wave ultrasonic imaging system demonstration. The design method comprises the following steps: determining thesize of the test block; determining character positions; determining fonts and font sizes of the characters; determining the position of the transverse through hole: drawing the shape of the characterthrough multiple line segments or arcs, dividing the multiple line segments and/or arcs into a plurality of parts, drawing a circle representing the transverse through hole at each division point, determining the position of the transverse through hole on the test block, and obtaining a character sketch; and carrying out verification: importing the character sketch into ultrasonic simulation software, placing a transverse through hole with a designed size in each circular area, selecting plane wave imaging, carrying out simulation calculation, and determining the effectiveness of the test block. According to the design method of the verification test block suitable for plane wave ultrasonic imaging system demonstration, the through transverse through hole is formed in the thickness direction of the test block to form the character, when the verification test block performs plane wave imaging, the probe only needs to move in the length direction of the test block, the demonstration program speed is high, and the thickness of the test block is not limited.

Description

technical field [0001] The invention specifically relates to a design method of a verification test block suitable for the demonstration of a plane wave ultrasonic imaging system and a verification test block suitable for the demonstration of a plane wave ultrasonic imaging system prepared according to the design method. Background technique [0002] In recent years, with the increasingly powerful computer hardware level and the increasingly mature software algorithm, phased array ultrasonic imaging has been more and more widely used in industry. C-scan imaging based on phased array ultrasound is also widely used in testing the performance of ultrasonic testing equipment and promoting the brand of instrument manufacturers or non-destructive testing units. In the existing phased array ultrasonic demonstration test block, the demonstration characters are engraved on the thin metal plate in the form of shallow grooves, such as figure 1 shown. During the demonstration, a linea...
