Abstract

The invention provides an ultrasonic probe, which can avoid the problem of high attenuation caused by the use of vulcanized silicone rubber material for the acoustic lens. The ultrasonic probe includes: a matching element, a back layer, a piezoelectric element and a driver; the piezoelectric element is located on Between the matching element and the back layer; the driver generates a coded waveform and inputs it to the piezoelectric element, so that the piezoelectric element outputs a focused sound wave field along the short axis of the piezoelectric element.

Description

technical field [0001] The present invention relates to an ultrasonic probe, and in particular to an ultrasonic probe capable of generating a focused sound wave field. Background technique [0002] A general ultrasonic probe is focused on the short axis by using an acoustic lens (acoustic lens) to detect the tissue of the object to be measured. Acoustic lenses generally use silicone rubber vulcanizate (RTV) material. However, such materials suffer from high attenuation. Therefore, it is urgent to propose a new short-axis focusing scheme. Contents of the invention [0003] The invention provides an ultrasonic probe, which can avoid the problem of high attenuation caused by the use of vulcanized silicone rubber material for the acoustic lens. [0004] In a first aspect, the present invention provides an ultrasonic probe, comprising: a matching element, a back layer, a piezoelectric element, and a driver; the piezoelectric element is arranged between the matching element a...
