The present invention relates to an ultrasonographic device and an ultrasonographic method, and particularly to an ultrasonographic device and an ultrasonographic method that can accurately extract a boundary (contour) of a target tissue such as an organ or the like.
In an ultrasonographic diagnosis using an ultrasonographic device, information on a boundary (contour) of an organ or the like to which attention is paid is effective information. For example, with respect to an organ such as a heart or the like, it is effective to diagnosis that a boundary (contour) of the left ventricle is extracted and the area surrounded by the boundary (contour) concerned is determined or the volume of the left ventricle is estimated on the basis of the boundary (contour).
For example, a prior art described in Patent Document 1 is known as a technique of extracting and displaying a boundary (contour) of a tissue.
