An object is to simultaneously visualize a plurality of junction surfaces of a workpiece. An ultrasound imaging device serving as solution means includes a signal processing unit that causes a probe to irradiate a workpiece with an ultrasound wave having a predetermined frequency, and that performs gate processing on a reflected wave of the ultrasound wave detected by the probe so as to output a displacement of the reflected wave on two junction surfaces of the workpiece, an image generation unit that generates respective images of the two junction surfaces, based on the displacement of the respective reflected waves on the two junction surfaces, and a height adjustment unit that adjusts a height of a focus of the probe. The height adjustment unit adjusts the height of the probe so as to set the focus of the probe between the two junction surfaces.

Ultrasound imaging device and method of generating image for ultrasound imaging device

An ultrasonic imaging device includes an ultrasonic probe including a piezoelectric device transmitting ultrasonic waves to a sample and receiving echo waves, an X axis scanner and a Y axis scanner scanning the sample and positions the probe at a scanning position, a frequency controller controlling a frequency of a received signal in accordance with the position of the scanning position, a signal processing unit processing the received signal, and an image generator generating an ultrasonic wave image at the frequency based on an output of the signal processing unit. The frequency controller generates and supplies a burst signal having a predetermined frequency by a burst wave oscillator to the piezoelectric device of the ultrasonic probe to generate the ultrasonic waves having a predetermined frequency.
