Abstract: An ultrasound diagnosis apparatus according to an embodiment includes processing circuitry. The processing circuitry includes: transmitter/receiver circuitry configured to transmit an ultrasound wave to the inside of an examined subject and to receive an echo signal emitted in response to the ultrasound wave; and processing circuitry configured to extract, with respect to each spatial point, information that is related to motion velocity of a target inside the examined subject and included in a signal data sequence obtained from the echo signal, to calculate periodicity information of a movement of the examined subject on the basis of the information, and to generate a spatial distribution of the periodicity information.
