Under the power-on state, the piezoelectric material can generate elastic deformation, so that ultrasonic waves are generated; in the opposite case, when the ultrasonic wave passes through the piezoelectric material, it can generate elastic deformation, and then the voltage is changed. The backing material layer 24 serves to dampen vibrations from the piezoelectric material, shorten the wavelength and improve axial resolution. The ultrasound probe module generates a desired image by controlling an ultrasound signal transmitted therefrom or using a received ultrasound signal, and allows the image to be displayed in real time, without radiation exposure, with high safety.
