Provided is an ultrasonic diagnosis device including: an ultrasonic probe； an imaging unit that transmits and receives ultrasonic beams between the ultrasonic probe and an examination subject and that forms an image on the basis of the received signals output from the ultrasonic probe, thus generating an ultrasonic image of the examination subject； a display unit； a matching pattern memory in which a plurality of matching patterns that individually correspond to a plurality of examination sites in the examination subject are stored in advance； a confidence calculating unit that reads out the plurality of matching patterns from the matching pattern memory, and that performs site identification by individually matching the ultrasonic images generated by the imaging unit with the plurality of read-out matching patterns, thereby individually calculating degrees of confidence regarding whether or not the ultrasonic images indicate examination sites corresponding to the individual read-out matching patterns； and a dialog display control unit that determines whether or not to display, on the display unit, a dialog for allowing a user to check, on the basis of the degrees of confidence, if any of the plurality of examination sites, for which the degrees of confidence are individually calculated, correspond to sites at which the images are acquired in the examination subject, and that displays the dialog on the display unit depending on the determination result.La présente invention décrit un dispositif de diagnostic par ultrasons comprenant : une sonde ultrasonore ； une unité d'imagerie qui transmet et reçoit des faisceaux ultrasonores entre la sonde ultrasonore et un sujet d'examen et qui forme une image sur la base des signaux reçus émis depuis la sonde ultrasonore, générant ainsi une image ultrasonore du sujet d'examen ； une unité d'affichage ； une mémoire de motif de correspondance dans laquelle une pluralité de motifs de correspondance qui correspondent individuellemen
