PROBLEM TO BE SOLVED: To facilitate the imaging diagnosis by displaying the three-dimensional coordinate distribution chart of the tube thickness of a tube structural tissue. SOLUTION: A fly-through processing part 12 forms a three-dimensional tomographic image based on plural tomographic image stored in a data storing part 8 and displays this on a display part 11. An operator inputs the CT values of a view point, a tube-direction vector and a tube structural tissue to the desired tube structural tissue of the three-dimensional tomographic image by using an operation input part 14. A tube thickness displaying processing part 13 fetches information on a surface vertical to the extending direction of the tube structural lissue from the view point from a main storing part 7 an obtains the width (tube thickness) of a set CT value on each vertical surface by calculation in the range of 0 deg. to 360 deg.. The three-dimensional coordinate distribution chart expressing each angle, a position corresponding to the extending direction of the tube and the width (tube thickness) of the CT value on three-dimensional coordinates is prepared and this is displayed on the part 11. Thus, lesion part can easily be found. |
