Abstract

The invention discloses an ultrasonic detection imaging method. The method includes the following steps that first, a stepping motor drives a foldable multi-stage rotating ultrasonic probe, an ultrasonic probe body of the foldable multi-stage rotating ultrasonic probe transmits an ultrasonic signal, and an ultrasonic echo detection signal is collected and transmitted to a detection host; second, a signal processing module positions and calculates the position of the ultrasonic probe body, and position information is transmitted to the detection host; third, the ultrasonic echo detection signal picked by the detection host is imaged through the detection host, image splicing is performed according to the position information, and an image of a detected target is obtained; fourth, an image display displays the image. The invention further discloses a device for implementing the ultrasonic detection imaging method. The device comprises a sucker, the image display, the detection host, a power module, a signal processing module and the foldable multi-stage rotating ultrasonic probe. The device has the advantages of being simple in structure, easy to operate, convenient to control, high in accuracy and the like.

Description

technical field [0001] The invention relates to an ultrasonic detection technology with a flexible and adjustable detection range, in particular to an ultrasonic detection imaging method and device. Background technique [0002] With the development of science and technology, the ultrasonic detection technology that requires flexibility in the detection area and detects the internal characteristics of the detection object is becoming more and more important. This type of detection technology is widely used in industrial, medical, security and scientific research fields. , such as industrial ultrasonic detection, medical ultrasonic detection, etc., are inseparable from the flexible and changeable ultrasonic detection technology in the detection area. Therefore, ultrasonic detection technology with high precision, low cost and flexible detection area is particularly important and urgent. At present, there are mainly two methods of scanning detection for internal information o...
