Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation imaging systems face issues with radio wave interference, which can decrease communication speed and quality due to overlapping frequency bands used for short-range wireless communication and image transmission.
Innovation Solution
A radiation imaging apparatus with a control unit that manages communication forms for both first and second wireless communication units, allowing for changes based on the communication state of the radiographic image transmission to mitigate interference by altering frequencies or prioritizing communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If short range wireless communication unit is used to establish link with access point, then wireless communication capability is improved, but radio wave interference occurs due to overlapping frequency bands
Solution Approach 1:
The system dynamically switches between different communication modes (first wireless communication for image transmission, second wireless communication for link establishment) based on communication state. The control unit monitors communication conditions and adaptively changes which communication unit is active, preventing frequency interference while maintaining wireless functionality.
Solution Approach 2:
The wireless communication function is divided into two separate units: first wireless communication unit for radiographic image transmission and second wireless communication unit for link establishment. This segmentation allows each unit to operate independently on different frequency bands, eliminating interference between short-range communication and image transmission.
2Adaptability or versatility
If both first and second wireless communication units operate simultaneously, then communication functionality is improved, but communication speed and quality decrease due to interference
Solution Approach 1:
The control unit dynamically controls the operation state of first and second wireless communication units based on communication state. When radiographic image transmission is occurring, the second communication unit is controlled to avoid simultaneous operation, preventing interference and maintaining high communication quality.
Solution Approach 2:
The system uses periodic communication state monitoring and switches between communication modes in different time periods. During image transmission periods, only the first communication unit operates; during link maintenance periods, the second communication unit operates. This time-division approach ensures reliable communication without interference.

AI summary
A radiation imaging apparatus configured to perform radiation imaging includes a first communication unit configured to transmit a radiographic image with an access point included in a radiation imaging system, a second communication unit configured to perform second wireless communication for transmitting and receiving information for establishing wireless communication with a communication device included in the radiation imaging system, and a control unit configured to control wireless communications of the the first and second communication units. The control unit performs control to change a communication form of the wireless communication of at least one of the first and second communication units based on a communication state in transmission of the radiographic image through the first wireless communication.
