Radiographic Image Display Control for Intermittent Frame Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiographic imaging systems face challenges in displaying frames at necessary timings due to low wireless communication speeds between the radiographic imaging apparatus and the display device, leading to delayed frame display and misalignment of images captured during intermittent imaging sessions.
Innovation Solution
A radiographic imaging control apparatus and method that prioritizes displaying images from later intermittent imaging sessions over earlier ones, ensuring timely display of frames by stopping the acquisition of frames from previous sessions and focusing on new frames during subsequent imaging sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If frames are transmitted wirelessly from the radiographic imaging apparatus to the display device, then the display device can show captured images, but the frame display is delayed due to low wireless communication speed
Solution Approach 1:
The system performs preliminary actions by pre-transmitting or pre-buffering frame data before it is actually needed for display. The display device prepares to receive and display frames in advance, and the imaging apparatus prioritizes transmitting frames that will be needed soonest, reducing the actual display delay when wireless transmission occurs.
Solution Approach 2:
The system implements feedback mechanisms where the display device monitors its frame reception and display status, then communicates this information back to the imaging apparatus. This allows the imaging apparatus to adjust its transmission priorities and timing based on actual display needs, ensuring frames are transmitted at optimal moments to minimize display delays.
2Quantity of substance
If multiple intermittent imaging sessions are performed, then more diagnostic images are obtained, but frames from earlier sessions are displayed at later sessions due to transmission delays
Solution Approach 1:
The system segments the frame transmission and display process by session, treating each intermittent imaging session as a distinct unit with its own priority level. Frames from more recent sessions are assigned higher priority for transmission and display, ensuring that the most current diagnostic information is always prominently displayed while still preserving access to historical session data.
Solution Approach 2:
The system dynamically adjusts transmission priorities based on the timing and sequence of imaging sessions. As new sessions are initiated, the system automatically re priorities the transmission queue to favor frames from the most recent sessions, creating a dynamic prioritization scheme that adapts to the current diagnostic needs while maintaining accurate temporal correspondence between captured and displayed frames.
Data Source
AI summary
A radiographic imaging control apparatus includes a hardware processor and outputs a display-purpose image generated based on a series of frames, the series of frames being captured by moving image capturing of a subject with radiation. When the moving image capturing is intermittently performed multiple times from one time of imaging start to one time of imaging end, the hardware processor prioritizes displaying a display-purpose image of second moving image capturing over displaying a display-purpose image of first moving image capturing The second moving image capturing is performed later than the first moving image capturing.
