Claim:
1. A three dimensional orientation configuration apparatus comprising: a processor configured to perform, generating a two-dimensional projection image from a three dimensional image indicating a three dimensional object; receiving the designation of a two-dimensional target point which is a target point on the projection image, setting a three dimensional target point corresponding to the two-dimensional target point to the three dimensional image, setting a reference cross-section to the three dimensional image on the basis of the three dimensional target point, generating a cross-sectional two-dimensional image of the reference cross-section in which an object located on a point of view side of the reference cross-section included in the three dimensional image is not displayed, the point of view is located on a line that passes through the three dimensional target point and the line is perpendicular to the reference cross-section and the point of view faces the reference cross-section, displaying the cross-sectional two-dimensional image on a display unit, and generating the projection image, displaying the projection image, receiving the designation of the two-dimensional target point, setting the three dimensional target point, setting the reference cross-section, generating the cross-sectional two-dimensional image, displaying the cross-sectional two-dimensional image, receiving an instruction to change the position of a point of view, using the three dimensional target point based on the cross-sectional two-dimensional image as a reference point, in order to align an observation direction of a structure to which the three dimensional target point is set with a target three dimensional direction, sets a new reference cross-section on the basis of the changed position of the point of view, generating a new cross-sectional two-dimensional image of the new reference cross-section, and displaying the new cross-sectional two-dimensional image to determine a three dimensional direction for observing the three dimensional image.
