Dynamic Image Failure Frame Identification in Radiation Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiation imaging, dynamic images with multiple frames pose challenges in identifying the reason for failure, as all frames are not failures, making it difficult to determine the cause of image failure, unlike static images where techniques exist.
Innovation Solution
An image display apparatus that obtains and analyzes data from dynamic images, allowing users to specify or automatically identify failure frames within the dynamic image, highlighting the reason for failure, similar to static images.

Engineering Contradiction Analysis
1Object-affected harmful factors
If dynamic images with multiple frames are displayed to reduce unnecessary exposure, then radiation exposure is reduced, but it becomes difficult to determine the reason for failure in the dynamic image
Solution Approach 1:
The patent segments the dynamic image into individual frames and identifies specific failure frames within the sequence. By dividing the multi-frame dynamic image into discrete units and marking only the frames containing failures, the system enables easy identification of failure reasons while maintaining the benefit of reduced radiation exposure through selective display of failure frames rather than requiring review of all frames.
2Loss of information
If all frames in dynamic image are displayed for analysis, then complete information is provided, but it becomes difficult to quickly identify failure frames among non-failure frames
Solution Approach 1:
The patent applies visual differentiation (such as color changes or marking) to failure frames within the dynamic image sequence. This allows the system to maintain complete information by displaying all frames while simultaneously improving ease of operation by enabling users to quickly identify failure frames through their distinct visual appearance compared to non-failure frames.
3Manufacturing precision
If failure images are stored and analyzed to improve future imaging, then imaging quality improves, but the complexity of managing and displaying failure images increases
Solution Approach 1:
The patent extracts and isolates failure frames from the complete dynamic image sequence for separate management and display. By taking out only the relevant failure information rather than managing entire dynamic images or all frames, the system maintains imaging quality improvement through analysis while reducing the complexity of managing and displaying failure images.
Data Source
AI summary
An image display apparatus includes a display which can display an image; and a hardware processor. The hardware processor obtains image data of a dynamic image or a moving image including a plurality of frames generated by a radiation imaging apparatus. The hardware processor displays on the display as a failure image at least one failure frame included in the dynamic image or the moving image based on the obtained image data or analyzed image data obtained by analyzing the image data, the failure frame including a reason why the dynamic image or the moving image cannot be provided for diagnosis.
