Mobile Radiographic Imaging Apparatus Frame Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile radiographic imaging apparatuses face challenges in displaying moving images in real-time due to the large angle of view and high volume of image data from flat panel detectors, leading to delayed display of frames, especially when image transfer is slow, making it difficult for users to promptly verify changes during image capture.
Innovation Solution
The apparatus acquires a moving image composed of frames and displays a specific frame from the beginning and end of the series as still images, allowing for early verification of changes after image capture completion, even if image transfer is delayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image data from the flat panel detector is transferred wirelessly to prevent infection and improve ease of use, then infection prevention is improved, but image transfer time increases causing delayed display of frames
Solution Approach 1:
The patent extracts and prioritizes the transfer of only the first and last frames from the complete moving image sequence. By separating these key frames from the full sequence and transferring them first, the system enables early verification of procedural changes without waiting for complete image transfer, thus reducing the effective waiting time while maintaining wireless transfer for infection prevention
Solution Approach 2:
The system performs preliminary transfer of the first and last frames before the complete moving image sequence is transferred. This preliminary action allows users to verify procedural changes early, and the remaining frames are transferred in the background without interrupting the user workflow
2Loss of information
If all frames of the moving image are transferred before display to ensure complete image data is available, then image data completeness is improved, but display time is delayed making it difficult to verify changes promptly
Solution Approach 1:
The patent segments the moving image data into three parts: the first frame, the last frame, and the intermediate frames. The first and last frames are transferred and displayed immediately for verification, while intermediate frames are transferred in the background. This segmentation allows early verification without sacrificing complete image data availability
Solution Approach 2:
The first and last frames are extracted from the complete moving image sequence and prioritized for immediate transfer and display. These extracted frames contain the critical information needed for verification, allowing users to check procedural changes without waiting for the entire sequence
3Area of stationary object
If the flat panel detector uses a large angle of view to capture the entire procedure area, then imaging coverage is improved, but the volume of image data increases causing longer transfer times
Solution Approach 1:
The patent extracts only the essential frames (first and last) from the large-volume moving image data generated by the high-resolution flat panel detector. This extraction reduces the amount of data that needs to be transferred for verification purposes, while the complete high-resolution data remains available for later analysis if needed
