PROBLEM TO BE SOLVED: To provide a three-dimensional ultrasonography with a scanning method and displaying method so as to be capable of grasping the valve structure of heart in a short time. SOLUTION: In the ultrasonography capable of three-dimensional ultrasonic scanning of a three-dimensional area in an examinee body, a tomographic image producing means to two-dimensionally scan an arbitrary tomographic plane in the three-dimensionally scannable area by ultrasonic waves to produce a tomographic image corresponding to the tomographic plane, a region-of-interest setting means to set a region of interest on the tomographic image produced by the tomographic image producing means, a three-dimensional image producing means to three-dimensionally scan a region circumscribing the region of interest by the region-of-interest setting means to produce a three-dimensional image corresponding to the three-dimensional region, and a displaying means to collate positions of the three-dimensional image produced by the three-dimensional image producing means with the tomographic image to synthesize and display are provided.
