Tomographic Image Preview Filter Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing variety of filters for tomographic images makes it difficult for users to predict and select the appropriate filter for achieving desired quality, leading to challenges in filtering tomographic images effectively.
Innovation Solution
A tomographic image processing apparatus and method that generates and displays preview images by applying multiple filters to raw data corresponding to a selected cross-section of an object, allowing users to easily select and apply the desired filter for reconstructing images, with the ability to update preview images based on user input for different cross-sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple filters are provided for tomographic image processing, then the quality and variety of reconstructed images are improved, but the difficulty of filter selection and device complexity increase
Solution Approach 1:
The system performs preliminary actions by generating preview images that show the effect of each filter before the user makes a selection. This allows users to see the actual impact of different filters on the tomographic image data, making the selection process easier and more informed.
Solution Approach 2:
The system creates simplified copies (preview images) of the full reconstruction process for each filter option. These preview images are generated from the raw tomographic data and displayed to users, allowing them to compare filter effects without having to process or analyze complex raw data themselves.
2Manufacturing precision
If multiple filters are applied to generate preview images for the entire region, then comprehensive filter comparison is achieved, but the processing time is excessively long
Solution Approach 1:
The system segments the tomographic scan region into multiple sections and generates preview images for only selected cross-sections rather than processing the entire region. This segmentation approach allows users to evaluate filter effects on representative sections, significantly reducing processing time while maintaining the ability to assess filter quality.
Solution Approach 2:
The system performs partial action by generating preview images for a subset of cross-sections rather than all cross-sections in the scanned region. This partial processing provides sufficient information for filter selection without the excessive time cost of processing the complete dataset.
3Loss of information
If preview images are generated for the entire scanned region, then complete filter evaluation is possible, but the processing speed decreases
Solution Approach 1:
The system divides the scanned region into multiple sections and selects specific cross-sections for preview image generation. This segmentation enables the system to maintain filter evaluation capability while processing only representative sections, thereby improving processing speed without completely losing evaluation completeness.
Solution Approach 2:
The system extracts key information from the scanned region by selecting representative cross-sections for preview generation. By taking out only the essential portions needed for filter evaluation rather than processing the entire region, the system achieves faster processing while retaining sufficient information for effective filter selection.
