Bowl-shaped flexible three-dimensional array ultrasonic probe

Abstract

The invention aims at providing a bowl-shaped flexible three-dimensional array ultrasonic probe. The bowl-shaped flexible three-dimensional array ultrasonic probe has the advantages of locating accuracy, simple device and the like. The bowl-shaped flexible three-dimensional array ultrasonic probe comprises a bowl-shaped flexible shell, a composite piezoelectric crystal plate, a coupling agent injecting device, connecting lines and the like, wherein the bowl-shaped structure can well attach to the detected surface of a flexible body, an ultrasonic transducer adopts the multi-array-element array composite crystal plate structure, the plurality of array elements are distributed according to the Fibonacci helical line, 2n array elements compose the ultrasonic array transducer, according to the delaying sequence, each array element emits ultrasonic waves once, the other array elements including the emitting array element receive signals, and a storage records and stores the 2n signals. In combination with the phased array technology principle, the aperture synthesis technology is adopted for carrying out data after-treatment on the extracted 2n signals, and then the image reflecting the information including the position, degree and the like of the lesion tissue is obtained.

Description

technical field [0001] The invention relates to the field of medical lesion detection, in particular to a bowl-shaped flexible probe device that utilizes multi-composite wafer three-dimensional array ultrasonic technology to assist in detecting superficial (in vivo) lesions. Background technique [0002] The precise localization of lesions generally adopts preoperative imaging localization methods, such as ultrasound B imaging, X-ray detection, Doppler technology, etc. They have been used as important preoperative medical diagnosis methods, and their main function is to determine the location and nature of lesions, etc. Wait. Doctors usually design surgical incisions and remove lesions based on their own experience only based on the lesion information shown by imaging. Because the exact location of the lesion cannot be determined before surgery, a large incision is often required, and sometimes due to inaccurate positioning, it may be necessary to extend the incision and th...

AI Technical Summary

Problems solved by technology

[0004] First: A small incision is required to insert the endoscope into the human body for inspection. Although it is minimally invasive, it cannot achieve non-destructive detection of the lesion;

[0005] Second: For superficial lesions, the inspection process and equipment are too complicated and costly;

[0006] Third: The surface of the human body is uneven, and conventional testing equipment cannot fit the testing surface well
