An ultrasonic diagnosis apparatus may comprise: a probe comprising a transducer configured to transmit a signal to an object and configured to receive an echo signal from the object； a controller configured to control the probe； and/or an image generation unit configured to generate an image of the object based on the echo signal. The controller may be further configured to drive the transducer such that the signal transmitted simultaneously comprises a fundamental frequency and at least one harmonic. A method of generating an ultrasonic image may comprise: transmitting a signal to an object by using a transducer； receiving an echo signal from the object by using the transducer； and/or generating an image of the object based on the echo signal. The transmitting of the signal to the object may comprise driving the transducer such that the signal transmitted simultaneously comprises a fundamental frequency and at least one harmonic.
