A three-dimensional image display apparatus comprising: an image display control means that displays a three-dimensional visualization image on display means, the three-dimensional visualization image being obtained by three-dimensionally visualizing a structure of interest extracted from a three-dimensional image; a display condition setting means that sets display conditions including an orientation in which the three-dimensional visualization image is displayed; a storage means that correlates and stores designated display conditions and additional information, the designated display conditions being designated to add the additional information regarding the three-dimensional visualization image, the designated display conditions including an orientation for displaying the three-dimensional visualization image, and the additional information including at least one of text, annotations, objects of arbitrary shapes, and audio data; and being characterised by comprising: an allowable range setting means that sets an allowable range for the designated display conditions; and an information reproducing means that determines whether display conditions are within the allowable range of the designated display conditions when displaying the three-dimensional visualization image while changing the display condition and that enables the additional information correlated with the designated display conditions to be reproduced when an affirmative determination is made. an image display control means that displays a three-dimensional visualization image on display means, the three-dimensional visualization image being obtained by three-dimensionally visualizing a structure of interest extracted from a three-dimensional image; a display condition setting means that sets display conditions including an orientation in which the three-dimensional visualization image is displayed; a storage means that correlates and stores designated display conditions and additional information, the designated display conditions being designated to add the additional information regarding the three-dimensional visualization image, the designated display conditions including an orientation for displaying the three-dimensional visualization image, and the additional information including at least one of text, annotations, objects of arbitrary shapes, and audio data; and being characterised by comprising: an allowable range setting means that sets an allowable range for the designated display conditions; and an information reproducing means that determines whether display conditions are within the allowable range of the designated display conditions when displaying the three-dimensional visualization image while changing the display condition and that enables the additional information correlated with the designated display conditions to be reproduced when an affirmative determination is made. an allowable range setting means that sets an allowable range for the designated display conditions; and an information reproducing means that determines whether display conditions are within the allowable range of the designated display conditions when displaying the three-dimensional visualization image while changing the display condition and that enables the additional information correlated with the designated display conditions to be reproduced when an affirmative determination is made. <EOS>
