An ultrasound diagnosis apparatus includes filter coefficient acquiring circuitry configured to, based on a result of a principal component analysis using first data strings that are sets of data generated based on echo signals caused by transmission of ultrasound waves on the same scan line, obtain a filter coefficient that suppresses clutter components； deriving circuitry configured to use the filter coefficient to obtain, from target data strings contained in a region of interest among the first data strings, a second data string that is a set of data derived from echo signals based on a moving body present in the region of interest, and derive waveform information indicating temporal changes of the moving body by performing a frequency analysis on the second data string； and control circuitry configured to generate a waveform information image based on the wave information and cause a monitor to display the waveform information image.
