1. An image display apparatus, comprising:

  • a volume data acquisition unit which acquires volume data;

    an extraction unit which extracts a tubular object region from the volume data;

    a cross-sectional image creation unit which creates a plurality of cross-sectional images perpendicular to a center line of the extracted tubular object region;

    a projected image creation unit which creates a projected image;

    a display which displays said plurality of cross-sectional images and the projected image;

    a specification unit which specifies a respective arbitrary point on each of the plurality of cross-sectional images displayed on the display; and

    a controller which, according to the arbitrary points specified by the specification unit, superimposes at least two curved lines, including a planned wire line and a center line of the tubular object region, on the projected image on the display, wherein when a blood vessel center line and a planned wire line overlap with each other, the controller is configured to cause the blood vessel center line and the planned wire line to be displayed in such a manner that the blood vessel center line or the planned wire line closer to a viewpoint appears above the blood vessel center line or the planned wire that is farther from the viewpoint.
