Multimode three-dimensional ultrasound detection and imaging device and method

Abstract

The invention provides a multimode three-dimensional ultrasound detection and imaging device and method. The device comprises a box, an emission and reflection receiving spiral track, a transmission receiving spiral track, an emission and reflection receiving end, a transmission receiving end and a back-end processing system. When the device is used for detection, a detection object is arranged in the middle of the box and surrounded by the emission and reflection receiving spiral track and the transmission receiving spiral track. The emission and reflection receiving end can slide back and forth on the emission and reflection receiving spiral track and the transmission receiving end can slide back and forth on the transmission receiving spiral track for performing spiral three-dimensional scanning on the entire detection space. The multimode three-dimensional ultrasound detection and imaging device and method inverses a path (reflection channel) through which reflected ultrasonic waves pass and a path (transmission channel) through which transmitted ultrasonic waves pass through reflected wave information and transmitted wave information for further achieving three-dimensional imaging of characteristic distribution of the transmission channel and reflection channel. According to the multimode three-dimensional ultrasound detection and imaging device and method, the simple device is used for achieving fast and convenient detection, and the cost is low. The multimode three-dimensional ultrasound detection and imaging device and method can be expanded to non-medical application.

Description

technical field [0001] The invention relates to ultrasonic non-destructive detection technology, in particular to a device and method for inverting the parameter distribution of reflection channels and transmission channels by using ultrasonic propagation characteristics, and then performing multi-mode three-dimensional ultrasonic imaging. Background technique [0002] Non-destructive detection is to use the sound, light, magnetic and electrical characteristics of the material to detect whether there is a defect or inhomogeneity in the object to be inspected without damaging or affecting the performance of the object to be inspected, and to give the size and location of the defect , nature and quantity information. The result of non-destructive detection depends on the imaging of the detection target. Ultrasonic testing is one of the important means in the field of non-destructive testing. Due to its strong penetrating ability of detection signals, non-destructive, real-tim...

AI Technical Summary

Problems solved by technology

The current detection technology lacks a systematic point of view to describe the entire detection area, but only uses a single parameter to detect

X-ray CT (X-CT), γ-ray CT (γ-CT) and ultrasonic CT (UCT) are used to detect the attenuation coefficient or absorption coefficient of X-rays, γ-rays or ultrasonic waves passing through biological tissues. When this single parameter detection algorithm When the robustness is not good, it is easy to misdetect,

[0009] (3) Many detections are harmful to the detection object, especially to the human body

These tests cannot be tested for a long time and frequently, and the purpose of regular physical examination cannot be achieved.

[0010] (4) Expensive testing equipment

Equipment such as X-ray, nuclear magnetic resonance, and positron emission tomography are extremely expensive, and each inspection costs hundreds to thousands of yuan, so they cannot become routine medical examination items

[0011] (5) The detection device is complex and huge, and is greatly affected by the environment

The current CT equipment is very large, and it has high requirements on power supply, temperature, humidity, dust-free purification and other working environments, so it is difficult to expand its use in non-medical environments
