Abstract: Proposed are a method and an apparatus for visualizing a cross-sectional size of the root canal, the method being performed by at least one processor. The method may include displaying an image of a tooth by using CT image data of at least one tooth and three-dimensional rendering data of the root canal of the tooth, calculating, in response to a user selecting a target region of interest by using the image of the tooth, a cross-sectional size of at least a portion of the root canal included in the target region of interest, and displaying at least a portion of the calculated cross-sectional size by a visual factor.

Abstract: Disclosed are a method of and an apparatus for 3D visualization of the root canal curvature of a tooth. The method includes (a) displaying a CT image of one or more teeth on the basis of CT image data, (b) three-dimensionally rendering at least a portion of the root canal of a target tooth when a dental practitioner selects the target tooth from the CT image, and (c) visualizing a curvature in a region of the root canal that is three-dimensionally rendered using a visual factor.

Abstract: The disclosure is related to a display device that may produce and display a predetermined internal surface (e.g., a predetermined plane view) of an object according to a user input designating a depth thereof. Such display device may include a data storage, a user input interface, a processor, and an image display. The data storage may be configured to store image data. The user input interface may be configured to receive a request from a user. The processor may be configured to generate image data for a 3D image with internal surface images at one or more depths in response to the user request. The image display may be configured to display the 3D image with internal surfaces at each depth.

Abstract: The disclosure is related to displaying a three dimensional image and corresponding sectional images. A display device may include a data storage, an input interface, an image display, and a processor. The data storage may store image data. The input interface may receive position information of a first image point from a user. The image display may display a 3D image in a first display region and a sectional image of the 3D image in a second display region of the screen. The processor may generate the 3D image data to display the 3D image by locating the first image point of the 3D image at a first position in the first display region and the sectional image data to display the sectional image of the 3D image by locating a second image point of the sectional image at a second position in the second display region.
