It is possible to acquire the relationship between tomography data as a luminance value of an ultrasonic diagnostic image and elasticity data on a tissue in a target local region. ROI information calculation means divides an ROI into a plurality of divided regions. Displacement amount calculation means (21) calculates an inter-frame displacement amount, adds per-region information to a boundary of the divided regions, and outputs the displacement amount data to elasticity calculation means (22). The elasticity calculation means (22) calculates elasticity data according to the displacement amount. Elasticity information analysis means (23) calculates a representative value of the elasticity data on the actual tissue and outputs address information of the region other than the actual tissue to signal analysis means (17). The signal analysis means (17) calculates the representative value of the tomography data on the actual tissue according to the tomography data generated by ultrasonic diagnostic image calculation means (16) and the address information. The calculated tomography data and the elasticity data are displayed on display means (20) by various display methods.
