Radiation Image Processing Apparatus for Moving Image Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interpreting and diagnosing moving images captured with medical modalities is challenging due to the need for users to visually compare original and analyzed images, which can be burdensome and prone to misinterpretation, especially when dealing with large volumes of information that vary over time.
Innovation Solution
A radiation image processing apparatus that acquires and analyzes moving image data, selects specific analyzed frame images, derives calculation signal values from common pixel coordinates, and displays calculated images to facilitate intuitive comparison and diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple moving images are concurrently played back for comparison, then the user can access both original and analyzed images, but the user must manually shift views between target regions which increases interpretation time and operational complexity
Solution Approach 1:
The patent introduces an automatic image selection mechanism that acts as an intermediary between the user and the multiple concurrently displayed moving images. The system automatically identifies and selects corresponding target regions across different moving images based on anatomical landmarks or motion patterns, eliminating the need for manual view shifting while maintaining the ability to compare multiple images simultaneously
Solution Approach 2:
The patent replaces the manual mechanical operation of view shifting with an automated computational system. The hardware processor automatically performs image registration, landmark detection, and corresponding region identification across multiple moving images, substituting the manual mechanical view-shifting process with intelligent automated image analysis
2Reliability
If the user manually shifts views to compare target regions across moving images, then comparison is possible, but the frame image of interest may have already been played back making rewinding necessary which increases time consumption
Solution Approach 1:
The patent performs preliminary actions by pre-identifying and marking target regions in all concurrently displayed moving images before the user initiates comparison. The system detects anatomical landmarks and predicts target region positions in advance, so when the user wants to compare specific regions, the corresponding areas are already highlighted and ready for immediate comparison without requiring view shifting or rewinding
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors the playback status and position of multiple moving images, and automatically adjusts the display to keep corresponding target regions in view. When a target region is identified in one image, the system provides feedback by automatically positioning and highlighting the corresponding regions in other images, ensuring they are visible and synchronized without manual intervention
