3D Dentition Imaging for Precise Buccolingual Observation Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face difficulties in accurately designating the appropriate position for detailed observation in panoramic tomographic images of dentition, particularly in the buccolingual direction.
Innovation Solution
An image processing apparatus and method that generates three-dimensional image data of dentition constituent tissue, identifies segmentable regions, and develops a dentition image to display these regions at corresponding positions, allowing for precise detail observation through a predetermined reference position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If panoramic tomographic image is used for position designation, then overall dentition overview is obtained, but precise position designation in buccolingual direction becomes difficult
Solution Approach 1:
The patent transitions from two-dimensional panoramic view to three-dimensional virtual model, adding the buccolingual dimension to enable precise position designation in all three spatial directions while maintaining overall overview capability
2Measurement precision
If three-dimensional image data is generated and segmentable regions are identified, then precise position designation is enabled, but system complexity increases
Solution Approach 1:
The system automatically performs three-dimensional image generation, segmentable region identification, and correspondence position calculation without requiring complex manual intervention, allowing the system to serve itself in processing the imaging data
Solution Approach 2:
The system pre-generates three-dimensional image data and pre-identifies segmentable regions before actual position designation is needed, so that when position designation is required, the complex processing has already been completed

AI summary
An image processing apparatus that includes a storage storing image data obtained by CT imaging of dentition constituent tissue, a processor, and a display. The processor generates three-dimensional image data of the dentition constituent tissue, identifies a segmentable region in the dentition constituent tissue, identifies a three-dimensional position of the segmentable region, generates a dentition developed image, identifies a segmentable region corresponding position corresponding to the three-dimensional position in the dentition developed image, and displays, on the display, the dentition developed image in which the segmentable region is displayed at the segmentable region corresponding position. By designation of the segmentable region corresponding position, on the basis of a correspondence between the segmentable region corresponding position and the three-dimensional position, a detail observation image of the segmentable region is generated, and a detail observation reference position is determined according to a predetermined rule.
