In order to improve the quality of a three-dimensional elasticity image by establishing a method of evaluating the quality of the elasticity volume data, there is provided an ultrasonic diagnostic apparatus including: a two-dimensional elasticity image forming unit 116 that calculates elasticity frame data indicating the elasticity distribution measured by scanning an object in a three-dimensional manner using an ultrasonic wave; an elasticity volume data generation unit 117 that generates elasticity volume data by collecting the plurality of elasticity frame data items; a three-dimensional elasticity image forming unit 118 that forms a three-dimensional elasticity image by performing volume rendering of the elasticity volume data; and a quality calculation unit 121 that calculates 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 items, which are a basis for calculating the elasticity frame data, and a frame evaluation value indicating the quality of the elasticity frame data. |
