Ultrasonic diagnostic device, ultrasonic diagnostic device control method, and medical image diagnostic device

In the present invention, a pre-set condition storage unit stores a plurality of mother pre-set conditions for which at least image data gathering conditions are set beforehand, and assorted sub pre-set conditions set beforehand by updating all or a portion of image data gathering conditions included in each of the mother pre-set conditions, and from the pre-set condition storage unit the assorted sub pre-set conditions corresponding to the selected mother pre-set conditions are read. The sub pre-set condition suitable for ultrasonic examination of a subject is selected from among the assorted sub pre-set conditions that were read. With respect to the units involved in generating image data, image data gathering conditions based on the selected mother pre-set conditions are initialized, and image data gathering conditions are updated using the selected sub pre-set conditions. Image data is generated on the basis of the reception signals of ultrasonic transmission and reception that uses the updated image data
