PROBLEM TO BE SOLVED: To provide ultrasonic diagnostic equipment in which a user can easily check whether or not a treatment object is included in a region cauterized by a plurality of paracentesis needles.SOLUTION: Ultrasonic diagnostic equipment includes a needle position detection part for detecting positions and orientations of a plurality of paracentesis needles in a coordinate system in which a predetermined point in a three-dimensional space is an origin, and a display control part for causing a display part 6 to display a graphic G indicating a region surrounded by the plurality of paracentesis needles, which is a region of a polyhedron having two points in each of the plurality of paracentesis needles as apexes based on the positions and the orientations of the plurality of paracentesis needles detected by the needle position detection part.SELECTED DRAWING: Figure 8
