Patent ID: 8439839

Claim:
An ultrasonic diagnostic apparatus, comprising: an ultrasonic probe including a transducer for transmitting an ultrasonic wave and receiving the ultrasonic wave reflected by a tissue of a biological body, and a driving device, comprising one of a motor and an actuator, for changing a position of the transducer; a probe controller configured to control the driving device to change at least one of a direction and a position at which the transducer is to transmit the ultrasonic wave; a transmission processor configured to cause the transducer to transmit the ultrasonic wave a plurality of times in accordance with the position of the transducer; a receiving processor configured to receive the ultrasonic wave reflected by a blood vessel repeatedly using the transducer to generate a plurality of receiving signals; an intensity information generation processor configured to generate intensity information on a distribution of an intensity of the reflected ultrasonic wave based on the plurality of receiving signals; and a determination processor configured to specify a position of the transducer at which the intensity of the reflected ultrasonic wave is maximum, based on the intensity information; wherein the ultrasonic diagnostic apparatus transmits the ultrasonic wave at the specified position and calculates one of a property value and a shape measurement value of the blood vessel.
