Ultrasonic detection is used in many applications such as medical diagnosis, treatment, and ultrasonic inspection. As an example of the medical apparatus, an ultrasound imaging apparatus emits an ultrasound signal from a surface of a subject body toward a target site of the subject, and acquires a tomographic image of soft tissue or an image of blood flow using information of the reflected (or transmitted) ultrasound signal (ultrasound echo signal) without being invasive.

As shown in fig. 3, the ultrasonic probe 3 includes an acoustic lens layer 31, a matching layer 32, a piezoelectric sensor array layer 33, and a backing material layer 34. The acoustic lens layer 31 is an end directly contacting the organ to be detected to focus in the lateral and/or longitudinal directions. The matching layer 32 serves to reduce multiple reflections due to the difference in acoustic impedance between the skin and the acoustic lens layer 31. The piezoelectric sensor array element layer 33 includes a piezoelectric material, which may be a piezoelectric crystal or a composite piezoelectric material, and the geometric shape and size thereof may be designed according to the diagnostic scenario and requirements, including various shape designs such as a convex array, a linear array, etc., which are not limited herein. The piezoelectric sensor array element layer 33 is used for transmitting/receiving ultrasonic waves to complete the sound electricity and electricity-electricity conversion work, and can convert an electric signal into an ultrasonic signal and convert the ultrasonic signal into an electric signal, namely, the piezoelectric sensor array element layer has double functions of ultrasonic transmission and ultrasonic receiving.

In other embodiments, other antennas, such as monopole antennas, dipole antennas, etc., may be used in addition to the radar 4 for receiving and/or transmitting microwaves, and are not limited herein.

By using the tissue elastography principle, the physical pressure signal of clinical palpation is converted into a digital signal, an image of surface pressure distribution can be immediately generated, and two-dimensional and three-dimensional images of lesions can be displayed in real time. When the tactile sensor 21 touches the mammary gland and a certain pressure is applied by the extension device 22, the tactile sensor 21, i.e. the pressure sensor, can obtain the reaction forces generated by the tissues with different hardness, and then the information of the forces is detected by the tactile sensor 21 and converted into an electric signal through an electric circuit.
