In order to establish a method for evaluating the quality of elasticity volume data and increasing the quality of three-dimensional elasticity images, an ultrasound diagnostic device is disclosed provided with a two-dimensional elasticity image constructing unit (116) for calculating elasticity frame data representing the elasticity distribution measured by a three-dimensional ultrasound scan of a subject, an elasticity volume data generation unit (117) for gathering a plurality of elasticity frame data and generating elasticity volume data, a three-dimensional elasticity image constructing unit (118) for volume-rendering the elasticity volume data and constructing three-dimensional elasticity images, and a quality calculation unit (121) for calculating a volume evaluation value indicating the quality of the elasticity volume data on the basis of an autocorrelation value between a pair of tomographic frame data sets which is the basis of the elasticity frame data calculation and on the basis of a frame evaluation value indicating the quality of the elasticity frame data. |
