Ultrasonic probe and ultrasonic detection equipment with same

Abstract

The invention provides an ultrasonic probe and ultrasonic detection equipment with the same. The ultrasonic probe comprises an ultrasonic transducer array, a conduction device and an energy applying device; the ultrasonic transducer array is used for transmitting and receiving ultrasonic waves; the conduction device is arranged at the front end of the ultrasonic transducer array and comprises a fluid cavity filled with fluid, the fluid cavity is provided with an opening and an energy receiving port which are communicated with each other, and the opening is formed in the front surface of the conduction device and covered with an elastic film; the energy applying device is connected to the energy receiving port and used for applying energy to the fluid contained in the fluid cavity to enable the elastic film to vibrate to generate shear waves. According to the ultrasonic probe, the complete ultrasonic transducer array is adopted to receive ultrasonic wave signals containing shear wave information, the ultrasonic wave signals do not need to be made up through methods such as interpolating and beam forming, the measuring convenience and precision are improved, therefore, the imaging effect is good, the data processing amount is little, and the detection speed is high. In addition, the ultrasonic probe not only has an instantaneous elastic imaging function, but also has a traditional ultrasonic imaging and instantaneous elastic imaging composite function.

Description

technical field [0001] The invention relates to the technical field of ultrasonic detection, in particular to an ultrasonic probe and ultrasonic detection equipment with the ultrasonic probe. Background technique [0002] Transient elastography is a fast-growing non-invasive diagnostic technology. This technology uses mechanical vibration to generate low-frequency shear waves inside the tissue, and uses ultrasound to track the propagation of the shear wave inside the tissue. By analyzing the parameters of the shear wave Measure and calculate relevant information such as tissue elasticity and attenuation. At present, transient elastography is mainly used in non-invasive detection of liver fibrosis and fatty liver. [0003] Existing transient elastography equipment usually passes a vibrating column through the center of the B-ultrasound probe, and the vibrating column passes through the ultrasonic transducer array of the B-ultrasound probe. The transient elasticity imaging d...
