Claim 7:
8. An apparatus, comprising:
processing circuitry configured to
obtain first Doppler waveform data related to a left ventricular blood inflow; and
detect positions of an Early Wave (E-wave) and an Atrium Wave (A-wave) in the first Doppler waveform data, by using the first Doppler waveform data and a trained model trained with training data that includes at least positions of an E-wave and an A-wave in each of a plurality of pieces of second Doppler waveform data related to left ventricular blood inflows and the plurality of pieces of second Doppler waveform data,

wherein the plurality of pieces of second Doppler waveform data include at least Doppler waveform data containing aliasing of a Doppler waveform.
