MEDICAL IMAGE DIAGNOSIS DEVICE AND REGION-OF-INTEREST SETTING METHOD THEREFORE
First Claim
1. A medical image diagnosis device, characterized by comprising:
- a medical image acquiring unit that acquires a medical image;
a three-dimensional image constructing unit that constructs a three-dimensional image containing a motional internal organ region in the medical image;
a sectional image generator that generates a two-dimensional sectional image serving as a reference image from the three-dimensional image;
a region dividing unit that divides the reference image into a plurality of regions on the basis of a criterion for region division; and
a region-of-interest setting unit that calculates motion states of the plurality of regions, specifies at least one region of the plurality of regions on the basis of the calculated motion states, and sets a region in the medical image including the specified region as a region of interest.

Abstract
A medical image diagnosis device according to the present invention has a medical image acquiring unit that acquires a medical image, a three-dimensional image constructing unit that constructs a three-dimensional image containing a motional internal organ region in the medical image, a sectional image generator that generates a two-dimensional sectional image serving as a reference image from the three-dimensional image, a region dividing unit that divides the reference image into plural regions on the basis of a criterion for region division, and a region-of-interest setting unit that calculates motion states of the plural regions, specifies at least one region of the plural regions on the basis of the calculated motion states, and sets as a region of interest a region of the medical image in which the specified region is contained.

12. A region-of-interest setting method for a medical image diagnosis device, characterized by comprising:
-
a first step of acquiring a medical image by a medical image acquiring unit; a second step of constructing a three-dimensional image containing a motional internal organ region in the medical image by a three-dimensional image constructing unit; a third step of generating a two-dimensional sectional image serving as a reference image from the three-dimensional image by a sectional image generator; a fourth step of dividing the reference image into a plurality of regions on the basis of a criterion for region division by a region diving unit; and a fifth step of calculating motion states of the plurality of regions, specifying at least one region out of the plurality of regions on the basis of the calculated motion states and setting a region in the medical image including the specified region as a region of interest by a region-of-interest setting unit. - View Dependent Claims (14, 15, 16, 17, 18)
