Composite Oral Display Alignment for X-Ray and 3D Scan Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental systems do not provide a composite display of X-ray images and three-dimensional scans of oral areas, requiring dental professionals to mentally correlate common structures, which is imprecise and prone to errors.
Innovation Solution
A system and method that generates a composite display by aligning X-ray image data with three-dimensional model data, using edge determination, rough correlation, and fine correlation techniques to create a synchronized view of both types of data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If X-ray images and three-dimensional scans are viewed side-by-side separately, then both types of information can be displayed, but the dental professional must mentally correlate common structures which is imprecise and prone to errors
Solution Approach 1:
The patent merges X-ray images and three-dimensional scans into a single composite display where corresponding structures are spatially aligned and visually integrated. The system overlays or adjacently positions the X-ray image with the three-dimensional model such that common anatomical structures (teeth, jaws, surrounding structures) are correlated in the same visual field, eliminating the need for mental correlation while maintaining information integrity.
2Measurement precision
If a composite display is generated by aligning and correlating X-ray image data with three-dimensional model data, then structure correlation precision is improved, but the processing complexity and computational requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-processing X-ray image data and three-dimensional scan data separately before composite display generation. This includes extracting relevant structures, pre-aligning coordinate systems, and preparing data formats that facilitate accurate correlation. By preparing data in advance with proper spatial references and structural identifiers, the actual composite generation requires less complex real-time processing.
Solution Approach 2:
The patent employs an intermediary processing layer that translates and correlates data between the X-ray imaging modality and the three-dimensional scanning modality. This intermediary system uses registration algorithms, coordinate transformation, and feature matching to bridge the two different data types, enabling precise structural correlation without requiring direct complex interaction between the original data sources.

AI summary
Apparatuses, systems, and methods are provided for generating composite displays of oral areas. To generate the composite display, X-ray image data from an X-ray scan of an oral area of an individual and a three-dimensional model generated from a three-dimensional scan of the oral area of the individual are used. The X-ray image is correlated to a rendering generated from the three-dimensional model in the composite display such that structures in the X-ray image are matched to structures in the rendering.
