Abstract

An apparatus for generating a cross-sectional abdominal image includes a memory for storing a cross-sectional abdominal image, a measuring unit for measuring an outline of an abdomen, and a controller configured to correct the cross-sectional abdominal image based on the outline of the abdomen measured by the measuring unit.

First claim

The invention claimed is:

1. An apparatus for generating a cross-sectional abdominal image comprising:
a memory for provisionally storing a plurality of cross-sectional abdominal images;
a measuring unit for measuring an outline of an abdomen; and
a controller configured to correct a cross-sectional abdominal image, corresponding to the outline measured by the measuring unit, of the plurality of cross-sectional abdominal images based on the outline.

2. The apparatus for generating a cross-sectional abdominal image according to claim 1 ,
wherein the memory stores the plurality of cross-sectional abdominal images having different ranges of a visceral fat area and a subcutaneous fat area, and
the controller calculates a shape characteristic from the outline of the abdomen, estimates at least one of the visceral fat area and the subcutaneous fat area of the abdomen based on the shape characteristic, and then selects and corrects the cross-sectional abdominal image corresponding to the estimated at least one of the visceral fat area and the subcutaneous fat area.

3. The apparatus for generating a cross-sectional abdominal image according to claim 1 ,
wherein the cross-sectional abdominal image is a CT image acquired in a recumbent state.

4. The apparatus for generating a cross-sectional abdominal image according to claim 1 ,
wherein the outline of the abdomen is an outline acquired by measuring a subject in an upright state.

5. The apparatus for generating a cross-sectional abdominal image according to claim 1 ,
wherein the controller corrects the cross-sectional abdominal image based on an aspect ratio of the outline of the abdomen.

6. The apparatus for generating a cross-sectional abdominal image according to claim 1 ,
wherein the controller corrects the cross-sectional abdominal image such that the outline of the cross-sectional abdominal image matches the outline of the abdomen.

7. The apparatus for generating a cross-sectional abdominal image according to claim 1 ,
wherein the controller displays the corrected cross-sectional abdominal image on a display.

8. A method for generating a cross-section abdominal image comprising:
storing, provisionally, a plurality of cross-sectional abdominal images in a memory;
measuring an outline of an abdomen; and
correcting, corresponding to the measured outline, the cross-sectional abdominal image of the plurality of cross-sectional abdominal images, based on the measured outline.

9. The method for generating a cross-sectional abdominal image according to claim 8 , further comprising:
storing the plurality of cross-sectional abdominal images having different ranges of a visceral fat area and a subcutaneous fat area;
calculating a shape characteristic from the outline of the abdomen;
estimating at least one of the visceral fat area and the subcutaneous fat area of the abdomen based on the shape characteristic; and
selecting and correcting the cross-sectional abdominal image corresponding to the estimated at least one of the visceral fat area and the subcutaneous fat area.

10. The method for generating a cross-sectional abdominal image according to claim 8 ,
wherein the cross-sectional abdominal image is a CT image acquired in a recumbent state.

11. The method for generating a cross-sectional abdominal image according to claim 8 ,
wherein the outline of the abdomen is an outline acquired by measuring a subject in an upright state.

12. The method for generating a cross-sectional abdominal image according to claim 8 , further comprising correcting the cross-sectional abdominal image based on an aspect ratio of the outline of the abdomen.

13. The method for generating a cross-sectional abdominal image according to claim 8 , further comprising correcting the cross-sectional abdominal image such that the outline of the cross-sectional abdominal image matches the outline of the abdomen.

14. The method for generating a cross-sectional abdominal image according to claim 8 , further comprising displaying the corrected cross-sectional abdominal image on a display.
