PROBLEM TO BE SOLVED: To provide a Doppler spectrum waveform that is easy to measure for an operator in a Doppler mode of an ultrasonic diagnostic apparatus.SOLUTION: An ultrasonic diagnostic apparatus 1 includes: a transmission/reception unit 4 that transmits/receives ultrasonic waves with a part to be diagnosed including a moving body in a subject; a Doppler signal detection unit 62 that extracts a Doppler signal on the basis of a reception signal obtained by the transmission/reception unit 4; a spectrum generation unit 64 that performs a frequency analysis on the basis of the Doppler signal and generates a Doppler spectrum; a luminance information control unit 2a that determines a luminance corrected value according to a frequency subjected to the frequency analysis and controls luminance information of the Doppler spectrum on the basis of the luminance corrected value; and a display device 10 that displays a Doppler spectrum after the luminance information has been controlled by the luminance information control unit 2a. |
