Ultrasound diagnosis apparatus and ultrasound signal generation method

An ultrasound diagnosis apparatus comprising:

• storage circuitry configured to store, in the storage circuitry, a trained model trained using a first ultrasound signal as input data and a second ultrasound signal as target data, the first ultrasound signal containing a saturated signal, effect of saturation being reduced in the second ultrasound signal from the first ultrasound signal;
• and
• processing circuitry configured to;
• input, to the trained model, a third ultrasound signal containing a saturated signal;
• acquire a fourth ultrasound signal output from the trained model to generate the fourth ultrasound signal, effect of saturation being reduced in the fourth ultrasound signal from the third ultrasound signal;
• and
• generate the first ultrasound signal and the third ultrasound signal by executing analog signal processing including clamping processing retraining a signal value, equal to or greater than a certain value, of an ultrasound signal to the certain value, the ultrasound signal being acquired by transmitting and receiving ultrasound to and from a subject,
• wherein the saturation occurs due to the clamping processing.
