An ultrasonographic device includes a template conversion unit (4) for templating tomogram information of a heart constructed by echo signals collected through an ultrasonic probe (1) brought into contact with an examinee so that the tomogram information can be correlated with templated diagnosis image information stored in a database (6), a matching unit (5) for matching the tomogram information templated in the template conversion unit with the templated diagnosis image information stored in the database (6), and a display device (9) for displaying the matching result of the matching unit (5) on a real-time basis together with a tomogram of the heart constructed by the echo signals collected through the ultrasonic probe brought into contact with the examinee.
