Claim:
1. An ultrasonic diagnostic apparatus which is configured to execute an imaging mode of alternately executing a continuous wave Doppler mode of acquiring time-series continuous wave Doppler data by transmitting and receiving a continuous wave to and from an object and a B mode of acquiring tomogram data that represents luminance by transmitting and receiving a pulse wave to and from the object, the apparatus comprising: a Doppler processing circuitry configured to to calculate a transient response component generated due to switching between the continuous wave Doppler mode and the B mode; to subtract the calculated transient response component from the continuous wave Doppler data to generate a remainder of the continuous wave Doppler data; to generate Doppler spectrum information by using the remainder of the continuous wave Doppler data; and a display configured to display the Doppler spectrum information in a predetermined format.
