Abstract:
1. An ultrasonic diagnostic apparatus, comprising: a tomographic image constructing unit configured to construct a tomographic image on the basis of a reflection echo signal received by an ultrasonic probe configured to transmit ultrasonic waves to and receive ultrasonic waves from an examinee; an elasticity information calculating unit configured to calculate elasticity information at a tomographic site of the examinee on the basis of the reflection echo signal; an elasticity image constructing unit configured to construct an elasticity image on the basis of the elasticity information of a region-of-interest set by a first region-of-interest setting unit; an image combining unit configured to generate a composite image comprising the tomographic image and the elasticity image; an image display unit configured to display the composite image; a control unit configured to freeze the composite image; and a second region-of-interest setting unit configured to at least one of change the first region of interest and set a second region-of-interest on the frozen composite image; wherein when the first region-of-interest on the frozen composite image is changed by the second region-of-interest setting unit, the elasticity image constructing unit constructs an elasticity image of the changed first region-of-interest on the basis of stored elasticity information of a region including the first region-of-interest.
