Ultrasonic probe and manufacturing method for ultrasonic probe

Abstract

The invention relates to the technical field of ultrasonic imaging equipment and discloses an ultrasonic probe and a manufacturing method for the ultrasonic probe. The ultrasonic probe comprises a piezoelectric crystal plate, wherein row electrodes are arranged on the front surface of the piezoelectric crystal plate; matching layers are pasted to a plurality of rows of electrodes; each row electrode passes through the side wall of the piezoelectric crystal plate and extends to two sides of the rear surface of the piezoelectric crystal plate to form an edge-covering electrode; column electrodes are arranged on the rear surface of the piezoelectric crystal plate; transverse cutting grooves are formed between adjacent row electrodes; longitudinal cutting grooves are formed between adjacent column electrodes; the edge-covering electrodes and the column electrodes are connected to leads; the leads are connected to a circuit board. The ultrasonic probe is simple in structure; the cost and the process difficulty are reduced; the production efficiency of the ultrasonic probe is improved; the batch production is achieved; the condition that the process difficulty of the ultrasonic probe is additionally increased by the introduction of a conductive component can be avoided; the positions of the leads connected to the edge-covering electrodes and the column electrodes are not located on the ultrasonic propagation path; the reduction of the acoustic performance of the probe caused by the introduction of structures such as an electric connection plate is avoided; the imaging effect of the ultrasonic probe is improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic imaging equipment, in particular to an ultrasonic probe and a manufacturing method thereof. Background technique [0002] Ultrasound imaging is a widely used detection and diagnosis method, which has the advantages of non-destructive, cheap, convenient and reliable. The ultrasonic signal generated by the ultrasonic probe propagates in the opaque medium, receives information such as the intensity, frequency, time, and phase of the ultrasonic signal reflected in the opaque object, and processes the received signal to obtain the detected signal. A visual image of the distribution of structural acoustic properties inside an opaque medium. [0003] A one-dimensional linear array or convex array ultrasonic probe can be used to obtain a two-dimensional cross-sectional image of the internal structure of the detected object. In order to obtain more clearly visible image details, such as improving the p...
