Patent ID: 7666138

Claim:
An ultrasonic transmitting and receiving apparatus comprising: an ultrasonic transducer array including plural ultrasonic transducers for transmitting ultrasonic waves and receiving ultrasonic echoes reflected from an object to be inspected; drive signal generating means for generating drive signals for respectively driving said plural ultrasonic transducers; transmission control means for controlling said drive signal generating means such that ultrasonic waves transmitted from said plural ultrasonic transducers form at least one ultrasonic beam; signal processing means for performing reception focusing processing on plural detection signals obtained based on the ultrasonic echoes received by said plural ultrasonic transducers so as to form a reception focal point in at least one region within the object thereby obtaining plural detection signals relating to said at least one region; storage means for storing plural different acoustic pressure intensity profiles, each of said plural different acoustic pressure intensity profiles representing one of acoustic pressure intensity and acoustic pressure intensity ratios in plural regions included in an isochronal surface as a surface where ultrasonic beams reach in predetermined time elapsed from being transmitted; and a calculating unit configured for calculating image data relating to said at least one region on the basis of the plural detection signals relating to said at least one region and selected at least one of said plural different acoustic pressure intensity profiles.
