Dental Arch Panorama Tomogram Extraction from X-ray Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for obtaining a panorama tomogram in dental X-ray computer tomography require complex operations such as inputting multiple coordinate points or setting reference curves, making it difficult for operators to produce the image efficiently and effectively.
Innovation Solution
An image processing method that extracts dental arch projection data based on preset position and shape information from X-ray projection data, allowing for the generation of a panorama tomogram with a simple operation, such as selecting a 'panorama display' option, without the need for additional X-ray exposure or complex data reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional methods are used to obtain panorama tomogram from X-ray projection data, then the panorama tomogram can be produced, but complex operations such as inputting multiple coordinate points or setting reference curves are required
Solution Approach 1:
The system automatically identifies and extracts dental arch projection data from the X-ray projection data without requiring operator intervention for coordinate input or reference curve setting. The extraction is performed self-service through automated algorithms that detect anatomical features and generate the panorama tomogram directly from the acquired data
Solution Approach 2:
Position and shape information about the dental arch is stored in advance in the system memory. When panorama tomogram generation is requested, the pre-stored information is automatically applied to extract the relevant projection data, eliminating the need for real-time manual setup and reducing processing time
2Productivity
If conventional methods are used to obtain panorama tomogram, then the image can be displayed, but immense amount of time and effort is required for complicated operations
Solution Approach 1:
The system extracts only the necessary dental arch projection data from the complete X-ray projection data set using automated extraction based on pre-stored position and shape information. This selective extraction eliminates the need for complex manual operations while maintaining high processing efficiency by focusing computational resources on relevant data only
Solution Approach 2:
The same X-ray projection data acquisition system is used for both conventional CT imaging and panorama tomogram generation. The system provides multi-functionality by enabling panorama image production as an additional capability without requiring separate specialized equipment, thereby improving productivity while maintaining operational simplicity
