Abstract

An ultrasonic transmitting and receiving apparatus capable of scanning an object to be inspected in high density and in a short time by using nondiffracting beams. The ultrasonic transmitting and receiving apparatus includes: an ultrasonic transducer array including ultrasonic transducers arranged in a matrix form; a waveform information setting unit for setting waveform information to be used for transmitting a plurality of ultrasonic beams, each of which is synthesized by ultrasonic signals having amplitude and phase characteristics represented by Bessel function, within a predetermined period; and a drive signal generating unit for respectively generating drive signals for driving the ultrasonic transducers included in the ultrasonic transducer array on the basis of the waveform information set by the waveform information setting unit.
