To provide an ultrasonic transmitter-receiver or the like capable of obtaining high quality ultrasonic images with reduced effect of side lobes.

The ultrasonic transmitter-receiver includes: an ultrasonic transducer array 10 including a plurality of ultrasonic transducers; a drive signal generating unit 14 for generating drive signals for driving the plurality of ultrasonic transducers respectively; a transmission control unit 13 for controlling the drive signal generating unit such that ultrasonic waves transmitted from the plurality of ultrasonic transducers form at least one ultrasonic beam; a reception control unit 24 for performing a reception focusing processing on a plurality of detection signals obtained based on ultrasonic echoes to form a reception focal point thereby obtaining a plurality of measurement data; a storage unit 31 for storing a plurality of different acoustic pressure intensity profiles; and an original data calculating unit 32 for calculating image data based on the plurality of measurement data and the plurality of different acoustic pressure intensity profiles.
