Abstract
An ultrasound diagnosis apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to speculate saturation of reflected-wave signals observed before a phased addition process performed by using the reflected-wave signals, in accordance with an intensity of reflected-wave data generated through the phased addition process, the reflected-wave signals being generated by transmitting an ultrasound wave with respect to mutually the same scanning line, and the processing circuitry is configured 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.
