摘要：<p>The invention generates Doppler waveform images, the visibility of which is improved appropriately in accord with changes in measurement conditions. The ultrasound diagnostic apparatus is equipped with: a frequency-analyzing unit that generates frequency spectrum data on Doppler shift frequency components of ultrasonic waves that are received after being transmitted towards a subject and reflected in the subject; and a line data-generating unit for generating line data, wherein arrays of multiple pixels are stipulated according to the corresponding frequencies and each pixel value represents the magnitude of the Doppler shift frequency component, on the basis of the frequency spectrum data. The ultrasound diagnostic apparatus determines whether or not each pixel of line data at a previously appointed time point is a noise pixel, and the values of pixels that are determined to be noise pixels are adjusted by multiplying the pixel value with a weighting factor (w) of 0 to less than 1.</p>
