Display Orientation Adjustment Device And Adjustment Program For Medical Three-Dimensional Image

A display orientation adjustment device for a medical three-dimensional image, including:

• a means for making a display means display a medical three-dimensional image based on medical three-dimensional image data according to a predetermined three-dimensional reference coordinate system;
• a means for making the display means display a reference image to be used as a reference for adjustment of a display orientation of the medical three-dimensional image;
• an observation direction change command input means for inputting an observation direction change command for changing an observation direction of a display image displayed by the display means;
• an observation direction changing means for moving the whole display image including the medical three-dimensional image and the reference image according to an observation direction change command input by the observation direction change command input means;
• a display orientation change command input means for inputting a command for rotatively moving only the medical three-dimensional image of the medical three-dimensional image and the reference image displayed by the display means around a first image reference axis specified among image reference axes of the three-dimensional reference coordinate system;
• a display orientation changing means for rotatively moving only the medical three-dimensional image around the first image reference axis according to a display orientation change command input by the display orientation change command input means;
• and
• a first correcting means for correcting medical three-dimensional image data on the three-dimensional reference coordinate system according to the rotative movement of the medical three-dimensional image by the display orientation changing means.
