Radiation Imaging Cassette Mode Switching Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiation imaging systems, doctors face challenges in switching from wired to wireless mode due to uncertainty about battery charge completion or communication recovery, leading to unstable system operations and missed opportunities for returning to wireless mode during radiography procedures.
Innovation Solution
A radiation imaging system with a first judging section to assess battery charge level and communication conditions, and a second judging section to determine if radiography is completed, along with a notification section to inform the doctor when it is safe to switch to the wireless mode, ensuring timely and stable system operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the FPD cassette is used in wireless mode without plugging the cable, then handling flexibility is improved, but system stability deteriorates when battery charge is low or communication is unstable
Solution Approach 1:
The notification device provides feedback to the operator about battery charge levels and communication status, enabling informed decisions about mode switching. This feedback mechanism allows the system to maintain stability by alerting users when wired mode is necessary while preserving the flexibility of wireless operation during optimal conditions.
Solution Approach 2:
The notification device acts as an intermediary between the system's internal state (battery level, communication status) and the operator's decisions. It mediates the transition between wireless and wired modes by providing timely information that guides when to switch modes, thus resolving the contradiction between flexibility and stability.
2Speed
If the cable is unplugged during data transmission, then operation speed is improved, but system reliability deteriorates due to unstable operations
Solution Approach 1:
The notification device provides preliminary warning to the operator before data transmission begins or during transmission, alerting them not to unplug the cable. This preliminary action prevents the harmful effect of unplugging during transmission while maintaining the ability to operate quickly in wireless mode when conditions are optimal.
Solution Approach 2:
The notification device applies preliminary anti-action by warning against the action of unplugging the cable during transmission. This counteracts the potential harmful effect before it occurs, preserving system reliability while allowing fast wireless operation when appropriate.
3Productivity
If the doctor prioritizes continuation of radiography over switching communication mode, then productivity is improved, but opportunity for returning to wireless mode is lost
Solution Approach 1:
The notification device enables the system to serve itself by automatically monitoring battery levels and communication status, then notifying the operator when conditions are optimal for mode switching. This self-service approach allows doctors to maintain high productivity without missing switching opportunities, as the system proactively identifies optimal moments for transition.
Solution Approach 2:
The notification device replaces the need for manual monitoring and decision-making about mode switching. Instead of the doctor having to constantly check battery levels and communication status, the automated notification system substitutes this mechanical monitoring process, allowing the doctor to focus on radiography productivity while the system manages communication mode optimization.

AI summary
A radiation imaging system includes a radiation imaging cassette and a console device. A communication mode between the cassette and the console device is switchable between a wired mode and a wireless mode. Due to shortage of a battery of the cassette, the communication mode is switched to the wired mode to start charging the battery and send image data from the cassette to the console device through a cable. The console device has first and second judging sections. The first judging section judges whether or not a charge level of the battery exceeds a predetermined threshold value. The second judging section judges whether or not radiography is in progress. If it is judged that the charge level of the battery exceeds the predetermined threshold value and the radiography is not in progress, a window that indicates permission for switching to the wireless mode is displayed on a monitor.
