3. The medical image display apparatus according to claim 1 , wherein, as the information about the region of interest, the processing circuitry is further configured to cause information about a calcification region of a heart valve to be displayed.

4. A medical image display apparatus, comprising:
processing circuitry configured to:
obtain an image data set of volume data or image data at multiple points in time;
specify an image of interest indicating a cross-sectional plane including a heart valve from the image data set;
specify a calcification region of the heart valve based on data that is included in the image data set and corresponds to a region of interest including the heart valve;
project information about the calcification region, which exists in a direction perpendicular to the cross-sectional plane including the heart valve of the image of interest, onto the image of interest; and
cause the image of interest and the projected information about the calcification region to be displayed.

5. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to cause the information about the region of interest to be displayed in a position within the image of interest corresponding to the region of interest.

6. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to change a display mode of the information about one or more regions of interest in accordance with at least one of: a distance from the observation cross-sectional plane, a quantity of the one or more regions of interest corresponding to positions on the observation cross-sectional plane, and a pixel value of the one or more regions of interest.

7. The medical image display apparatus according to claim 6 , wherein
the processing circuitry is further configured to receive, from a user, a condition related to at least one of: the distance from the observation cross-sectional plane, the quantity of the regions of interest corresponding to the positions on the observation cross-sectional plane, and the pixel value of the one or more regions of interest, and
the processing circuitry is further configured to change the display mode of the information about the one or more regions of interest, based on the received condition.

8. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to cause information about one or more regions of interest in a closed region that at least partially includes the one or more regions of interest to be displayed.

9. The medical image display apparatus according to claim 8 , wherein the information about the one or more regions of interest is information about one of:
a quantity of the regions of interest present inside the closed region, and a pixel value of the one or more regions of interest.

10. The medical image display apparatus according to claim 1 , wherein
the processing circuitry is further configured to specify at least one piece of important image data from the image data set, and
the processing circuitry is further configured to cause only information about the region of interest in the at least one piece of important image data to be displayed.

11. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to cause the information about the region of interest to be displayed while being superimposed on the image of interest.

12. The medical image display apparatus according to claim 1 , wherein the processing circuitry is further configured to control a display mode of the information about the region of interest, based on one of: a spatial distance between the information about the region of interest and the observation cross-sectional plane of the image of interest, and a positional relationship between the information about the region of interest and the observation cross-sectional plane of the image of interest.

13. The medical image display apparatus according to claim 1 , wherein, based on a pixel value of the information about the region of interest, the processing circuitry is further configured to control a display mode of the information about the region of interest projected onto the image of interest.

14. The medical image display apparatus according to claim 8 , wherein
