Abstract:
1. An ultrasonic transmitting and receiving apparatus comprising: an ultrasonic transducer array including plural ultrasonic transducers for transmitting ultrasonic waves and receiving ultrasonic waves 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 to be transmitted from said plural ultrasonic transducers form a transmission beam to be transmitted in at least one sound ray direction; reception control means for performing reception focusing processing on plural detection signals obtained based on ultrasonic waves received by said plural ultrasonic transducers so as to generate sound ray data representing ultrasonic information relating to said at least one sound ray direction; storage means for storing plural kinds of filter coefficients related to plural sound ray directions, respectively; and filter processing means for performing filter processing on the sound ray data generated by said reception control means by using filter coefficients related to said at least one sound ray direction in which transmission and reception have been performed from among said plural kinds of filter coefficients.
