Embodiment Construction

[0037] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection scope of the present invention are not limited thereto.

[0038] like figure 1 As shown, it is a working schematic diagram of an embodiment of the ultrasonic coupling pad embedded with reflective particles according to the present invention. In this embodiment, the ultrasonic coupling pad has a planar structure, and the line array of reflection points 101 is arranged in a row-column array combining dots and lines. The upper surface of the ultrasonic coupling pad 102 is the ultrasonic probe contact surface 103, which is in contact with the ultrasonic probe during operation, and the lower surface is the detected tissue contact surface 104, which is in contact with the detected tissue surface during operation. Among them, the outer layer is in contact with the ultrasonic probe, and its texture is relatively ...

Abstract

The invention discloses a device for expanding an ultrasonic detection region and increasing detection precision and a method. The device consists of an ultrasonic coupling gasket and reflection grains embedded in an ultrasonic coupling gasket substrate, an outer layer material of the ultrasonic coupling gasket substrate is harder than an inner layer material of the ultrasonic coupling gasket substrate, both the outer layer and the inner layer of the ultrasonic coupling gasket are made of acoustic transmission materials, the sound velocity of ultrasonic waves transmitted in the ultrasonic coupling gasket is consistent, and the reflection grains are embedded in the outer layer material of the ultrasonic coupling gasket substrate and are arrayed. In the method, accurate position information is marked in an image detected by an ultrasonic probe by the reflection grains, an external and common coordinate system is built for local ultrasonic images obtained at different moments, prior information is provided for mosaic, fusion and registration of the local images, a registration arithmetic is simplified, fast mosaic and fusion of the detected images are realized, accordingly, the detection region is expanded, and super-resolution images are obtained.

Description

technical field [0001] The invention relates to ultrasonic non-destructive detection technology, in particular to a device and method for expanding the ultrasonic detection area and improving detection accuracy. Background technique [0002] In the past 20 years, with the advancement of science and technology, especially the development of computer technology and digital image processing technology, ultrasonic nondestructive detection and imaging technology has made great progress in probe design, signal processing and application software development, which has greatly improved the quality of ultrasonic imaging. Improvement, the scope of application is getting wider and wider. Ultrasound has strong penetrating power, and has the advantages of no damage to the detected tissue and no radiation, so it is widely used in medical treatment, industry, energy, archaeology, etc. [0003] There is an increasing need for super-resolution images in many ultrasound detection and imagin...
