Claims

[Claims for Utility Model Registration] The sample is the focal region of the focused ultrasonic beam. In an ultrasound microscope that obtains an ultrasonic image of a sample using reflected ultrasound obtained by two-dimensional scanning, only the impedance within a certain range of the 2-dimensional distribution of acoustic impedance of the sample is used. An ultrasonic microscope characterized by being equipped with a means for displaying.
