1. An apparatus, comprising:
processing circuitry configured to
obtain first ultrasound data related to a left ventricular blood inflow; and
obtain information corresponding to waveforms of Early Wave (E-wave) and Atrium Wave (A-wave) included in the first ultrasound data based on the obtained first ultrasound data and a trained model trained with training data that includes second ultrasound data related to a left ventricular blood inflow and waveforms of an E-wave and an A-wave included in the second ultrasound data,
wherein the first ultrasound data includes any of noise equal to or higher than a reference value, aliasing, or brightness equal to or lower than a reference value, and the information is obtained from the first ultrasound data by using the trained model.
