Wireless X-Ray Camera Master-Slave Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiographic image capturing systems, the mobility of X-ray image capturing apparatuses with integrated access point (AP) functions leads to unstable wireless communication, and the presence of two wireless communication paths reduces communication speed, especially when images need to be transmitted to a computer via a separate AP-equipped apparatus.
Innovation Solution
An information processing system that designates one connected image capturing apparatus as a master unit for wireless communication, allowing it to establish a stable transmission path by switching settings to ensure wired communication with the information processing apparatus, thereby eliminating the need for dual wireless communication paths and maintaining high-speed data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an X-ray image capturing apparatus with AP function is made movable to improve mobility, then ease of operation is improved, but wireless communication stability deteriorates
Solution Approach 1:
The patent introduces a wired connection as an intermediary between the image capturing apparatus and the information processing apparatus. When wired connection is available, it serves as a stable communication path, eliminating wireless instability while preserving mobility when wireless-only operation is needed.
2Adaptability or versatility
If two wireless communication paths are used to transmit images from non-AP apparatus through AP-equipped apparatus, then adaptability is improved, but communication speed deteriorates
Solution Approach 1:
The patent segments the communication paths by distinguishing between wired and wireless connections. It identifies and prioritizes the wired communication path when available, separating it from wireless paths to avoid the speed degradation caused by dual wireless hopping.
Solution Approach 2:
Instead of forcing all communications through wireless paths, the patent inverts the approach by preferring wired connection when available and only using wireless as fallback. This reverses the conventional assumption that wireless is the primary mode.
3Ease of operation
If wireless communication is used to maintain mobility, then ease of operation is improved, but communication stability deteriorates
Solution Approach 1:
The patent implements dynamic communication path selection that adapts to available connections. The system automatically switches between wired and wireless modes based on connection availability, making the communication method dynamic rather than static.

AI summary
An information processing system including an information processing apparatus that receives captured radiographic images captured by a plurality of image capturing apparatuses each having a wireless communication function and a wired apparatus that connects to the information processing apparatus in a wired manner, the information processing system includes a setting unit that sets, in a case where one of the plurality of image capturing apparatuses is connected to the wired apparatus, the connected image capturing apparatus as a master unit of wireless communication, and a communication unit that receives, via the image capturing apparatus set as the master unit, a captured image of a different image capturing apparatus that is received through wireless communication by the image capturing apparatus set as the master unit from the different image capturing apparatus set as a slave unit of wireless communication.
