Wireless Communication Priority in Portable Radiography Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiation image capturing systems, wireless communication between the radiation image capturing apparatus and the console can interfere with wireless communication between the console and external systems, leading to transmission delays or errors, particularly in environments where only one wireless communication method, such as wireless LAN, is available, which can result in lost image data or increased patient irradiation.
Innovation Solution
A radiation image capturing system that prioritizes one wireless communication channel over the other or uses separate channels for communication between the radiation image capturing apparatus and the console, and the console and external systems to prevent interference, with options including configuring the system to prohibit certain communications based on specific triggers or using different channels for each type of wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used between the radiation image capturing apparatus and the console, then mobility and ease of operation are improved, but communication interference with external systems occurs
Solution Approach 1:
The wireless communication function is divided into two separate communication units: a first wireless communication unit for communicating with the radiation image capturing apparatus, and a second wireless communication unit for communicating with external systems. This segmentation allows independent control and management of each communication channel, preventing interference between them while maintaining mobility benefits.
Solution Approach 2:
The control unit dynamically controls the first wireless communication unit based on the operation state of the radiation image capturing apparatus. When the apparatus is in a state that may cause communication interference, the control unit prohibits or adjusts the first wireless communication unit's operations, thereby adapting the communication behavior to current system conditions and preventing data loss.
2Device complexity
If wireless communication channels are shared between image data transmission and external system communication, then device complexity is reduced, but data loss and transmission errors increase
Solution Approach 1:
The wireless communication functionality is segmented into two distinct communication units with separate channels: the first wireless communication unit dedicated to image data transmission from the radiation image capturing apparatus, and the second wireless communication unit for external system communication. This physical or logical separation of communication channels eliminates interference between image data transmission and external system communication, preventing data loss while maintaining manageable system complexity.
3Adaptability or versatility
If wireless communication is used in environments with limited communication methods, then adaptability to facility constraints is improved, but communication interference worsens
Solution Approach 1:
The control unit dynamically adjusts the operation of the first wireless communication unit based on the operational state of the radiation image capturing apparatus. When the apparatus is performing operations that may cause wireless interference, the control unit prohibits or suspends image data transmission through the first wireless communication unit. This dynamic adaptation allows the system to function reliably in facility environments with limited communication options while preventing data loss during critical operations.

AI summary
Disclosed is a radiation image capturing system including a portable radiation image capturing apparatus and a portable console. The portable radiation image capturing apparatus can generate image data according to irradiated radiation and transmit the generated image data by wireless communication. The portable console includes a first wireless communication unit which can receive the image data transmitted from the radiation image capturing apparatus and a second wireless communication unit which can communicate with an external apparatus or system by wireless communication. The console gives priority to one wireless communication than the other between the wireless communication through the first wireless communication unit or the wireless communication through the second wireless communication unit.
