Abstract

An ultrasonic observing apparatus includes an ultrasonic wave transmitting and receiving apparatus for transmitting and receiving ultrasonic waves, a first scanning apparatus for moving the direction in which the ultrasonic wave transmitting and receiving apparatus transmits and receives waves so that a first ultrasonic tomographic image may be obtained, a second scanning apparatus for moving the direction in which the ultrasonic wave transmitting and receiving apparatus transmits and receives waves so that a second ultrasonic tomographic image intersecting with the first ultrasonic tomographic image may be obtained and a control apparatus for controlling the first scanning apparatus and second scanning apparatus as related with each other.
