Radiographing System Dose Index Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radiographing systems fail to manage dose indices effectively for composition images formed by combining multiple radiographic images, as dose indices are not attached to these images, making it difficult to perform dose management.
Innovation Solution
A radiographing system that includes a dose index calculation unit to analyze and calculate dose indices for individual images, an obtaining unit to determine a representative dose index, and a storage unit to store this index alongside the composition image, enabling effective dose management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radiographic images are combined to create a composition image, then the imaging coverage and diagnostic information are improved, but the dose management capability deteriorates because dose indices cannot be attached to the composition image
Solution Approach 1:
The patent extracts the dose index information from individual radiographic images and separates it from the image data itself. The dose index calculation unit calculates dose indices for each radiographic image, and the obtaining unit extracts a representative dose index from these calculated values. This extracted dose index is then attached to the composition image, allowing dose management information to be preserved independently while maintaining the benefits of image composition.
Solution Approach 2:
The patent introduces an intermediary mechanism - the dose index calculation and obtaining units - that acts as a bridge between the individual radiographic images and the composition image. This intermediary process calculates, selects, and attaches the representative dose index, enabling dose management information to be transferred to the composition image without directly combining the raw image data with dose information.
2Reliability
If dose indices are calculated for each individual radiographic image, then the radiation exposure information is preserved, but the complexity of managing multiple dose indices increases
Solution Approach 1:
The obtaining unit extracts a representative dose index from the multiple calculated dose indices by applying specific selection criteria. This extraction process simplifies the management complexity by reducing multiple dose index values to a single representative value that can be easily attached to and managed with the composition image, while still preserving the essential radiation exposure information.
Solution Approach 2:
The patent changes the parameter representation from multiple individual dose index values to a single representative dose index parameter. This parameter transformation maintains the reliability of radiation exposure information by using statistically meaningful representations (such as average, maximum, or minimum values) while significantly reducing the complexity of managing and storing dose index data.
