Patent ID: 7303529

Claim:
An ultrasonic diagnostic equipment comprising: a transmission ultrasonic wave generation unit which generates a transmission ultrasonic wave that has, at least, a first frequency component, and a second frequency component at a frequency higher than that of the first frequency component, and which generates the transmission ultrasonic wave by controlling the frequency of at least one of the first and second frequency components so that, in a case of transmitting the transmission ultrasonic wave to a patient and receiving a reflected wave therefrom, a difference frequency component between the first frequency component and the second frequency component as is included in the reflected wave may interact with a second harmonic wave of the first frequency component, and also by controlling a phase difference between the first frequency component and the second frequency component to control the interaction; a transmission unit which transmits the transmission ultrasonic wave including the first frequency component and the second frequency component to the patient; a reception unit which receives the reflected wave of the transmission ultrasonic wave from the patient; and an image generation unit which generates an ultrasonic image on the basis of the reflected wave.
