Three-dimensional image projection apparatus, three-dimensional image projection method, and three-dimensional image projection control program

A three-dimensional image projection method comprising:

• recognizing an inclination of a screen in a three-dimensional space, wherein the screen is a flat plate and configured to be movable three-dimensionally without changing a shape of the flat plate by a user;
• projecting a projection image of a three-dimensional image of an organ of a subject on the screen on the basis of the position of the screen;
• and
• changing parameters of three-dimensional image processing performed for the three-dimensional image, on the basis of a change in the inclination of the screen in the three-dimensional space to perform a rotation process for the projection image of the three-dimensional image projected on the screen.

A non-transitory computer recording medium storing a three-dimensional image projection control program that causes a computer to function as:

• a processor configured to
• recognize an inclination of a screen in a three-dimensional space, wherein the screen is a flat plate and configured to be movable three-dimensionally without changing a shape of the flat plate by a user;
• a projection unit control unit that controls a projection unit such that a projection image of an organ of a three-dimensional image of a subject is projected on the screen on the basis of the position of the screen;
• and
• the processor is configured to change parameters of three-dimensional image processing performed for the three-dimensional image, on the basis of a change in the inclination of the screen in the three-dimensional space to perform a rotation process for the projection image of the three-dimensional image projected on the screen.
