ABSTRACT:
An apparatus for observing a sound field of an ultrasonic wave, including a first unit which determines characteristic values of a medium at each point of a predetermined region by an ultrasonic wave having a sound field of an arbitrary form and a second unit which displays an output of the first unit as two-dimensional or three-dimensional distribution in the predetermined region, and allows control of the form of the sound field of the ultrasonic wave.
