PROBLEM TO BE SOLVED: To provide an ultrasonic transceiver capable of providing an ultrasonic image reducing an effect of a side lobe. SOLUTION: This ultrasonic transceiver includes an ultrasonic transducer array including a plurality of ultrasonic transducers, a driving signal generation part generating driving signals driving the plurality of ultrasonic transducers respectively, a scanning control part controlling the driving signal generation part so that the ultrasonic waves transmitted from the plurality of ultrasonic transducers form ultrasonic beams, a phase matching part finding a set of measurement values related to a plurality of regions in a subject by performing a receiving focus processing to a plurality of detected signals detected by the plurality of ultrasonic transducers, an acoustic ray memory storing the set of measurement values, a sound pressure intensity distribution formed by transmitting the ultrasonic beams, an intensity profile storage part storing a plurality of different sound pressure intensity profiles set based on the receiving focus processing performed by the signal processing means, and a matrix operation part calculating image data related to a plurality of regions based on the set of measurement values and the plurality of different sound pressure intensity profiles.
