Abstract: An ultrasound diagnosis apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured: to generate a piece of reflected-wave data by performing a phased addition process while using reflected-wave signals generated by transmitting an ultrasound wave with respect to mutually the same scanning line; to speculate a degree of saturation of the reflected-wave signals observed before the phased addition process on the basis of a relationship between signals and noise in a data sequence represented by a set made up of pieces of the reflected-wave data; and to output a result of the speculation. The processing circuitry is configured to cause a display to display data based on the result of the speculation.
