Abstract
An ultrasonic imaging apparatus comprises transducers for transmitting ultrasonic waves and receiving acoustic. The apparatus also transmits ultrasonic waves of different frequencies simultaneously from a plurality of transducers. The frequency characteristics of the transducers are determined in a manner so as to produce the function of frequency filters. An electric filter is additionally provided for compensation. Thus, crosstalk is eliminated even when the frequency difference between the transmitting ultrasonic waves is kept small.
