According to the ultrasonic array probe signal acquisition component and the probe provided by invention, the problem of probe temperature rising is effectively solved, the send-receive capacity of signals is improved, probe functions of testing image resolution ratio and sharpness are improved, and the impact of the probe array element signal crosstalk to imaging sharpness is decreased.

Description

technical field [0001] The invention relates to the technical field of ultrasonic probes, in particular to an ultrasonic array probe signal acquisition element, an ultrasonic array probe, a preparation method of the ultrasonic array probe signal acquisition element, and an ultrasonic array probe preparation method. Background technique [0002] Ultrasonic array probe is an important part of ultrasonic diagnostic imaging equipment. Its function is to convert the electrical signal excited by the host device into an ultrasonic signal that propagates in the soft tissue of the human body, and at the same time convert the ultrasonic signal reflected back from the human body into an electrical signal, which is carried out by the host. The processed and displayed ultrasound images in the human body are used for analysis and diagnosis by doctors. In the existing ultrasonic array probes, in order to obtain more detailed scanning images, it is often necessary to set more ultrasonic pro...

Problems solved by technology

In the existing ultrasonic array probes, in order to obtain more detailed scanning images, it is often necessary to set more ultrasonic probe array elements, which leads to a smaller size of a single ultrasonic probe array element, which can penetrate human tissue The ultrasonic signal is very weak; and the heat generated by the continuous excitation of the probe array vibration cannot be evacuated in time, resulting in local temperature rise inside and on the surface of the probe, affecting the comfort of the patient and adversely affecting the internal structure and performance of the probe; Or, the signal interference between the array elements of the ultrasound array probe has affected the further improvement of the clarity of ultrasound imaging
