Patent ID: 7985183

Claim:
An ultrasonic diagnostic equipment comprising: a transmission ultrasonic wave generation unit configured to generate a transmission ultrasonic wave to a patient and configured to receive a reflected wave therefrom, the transmission ultrasonic wave including, at least, a first fundamental wave, and a second fundamental wave at a frequency higher than that of the first fundamental wave, and the transmission ultrasonic wave generation unit configured to generate the transmission ultrasonic wave by controlling the frequency of at least one of the first and second fundamental waves so that a sum frequency component between the first fundamental wave and the second fundamental wave, as is included in the reflected wave, interacts with at least one of a second harmonic wave of the first fundamental wave and a second harmonic wave of the second fundamental wave, and also by controlling a phase of at least one of the first and second fundamental waves in order to control the interaction; a transmission unit configured to transmit the transmission ultrasonic wave to the patient; a reception unit configured to receive the reflected wave of the transmission ultrasonic wave from the patient; and an image generation unit configured to generate an ultrasonic image on the basis of the reflected wave.
