ULTRASONOGRAPH

PROBLEM TO BE SOLVED: To provide an ultrasonograph capable of changing scanning conditions such as the numbers of transmitting/focusing stages and a frame rate without stopping processes relating to the scanning and an image formation, and image displays. SOLUTION: Each component includes: a control data storage section which has first and second regions for storing control data corresponding to the scanning conditions; and a region changeover section which controls the first and second storage regions between a region in which the control data are written and a region from which the control data are read. The control data corresponding to the scanning conditions after the change are written in either one of the first and second storage regions, the region changeover section controls to change therebetween and the written control data are read, so that the component is operated by the control data corresponding to the scanning conditions after the change.
