Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radiation image capturing systems face limitations in high-rate transmission of large amounts of radiation image information, as the amount of data remains unchanged, restricting efficient data transfer.
Innovation Solution
The system employs an amplitude/phase-modulated signal generated by combining and modulating serial signals from multiple radiation conversion panels, reducing data transmission requirements by half, and utilizing optical fibers for high-rate data transfer between the radiation detector and controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If optical fibers are used to transmit radiation image information, then transmission rate is improved, but data volume remains large and transmission efficiency is limited
Solution Approach 1:
The radiation conversion panel is divided into multiple detection areas (first detection area and second detection area), and data from each area is processed and transmitted separately. This segmentation allows for more efficient data management and transmission, reducing the overall data volume that needs to be transmitted through the optical fiber connection.
Solution Approach 2:
The patent extracts and transmits only the necessary data elements from the radiation image information. By identifying and transmitting only relevant data from the detection areas rather than all raw data, the system reduces transmission data volume while maintaining diagnostic quality.
2Measurement precision
If radiation conversion panels with more pixels and larger area are used, then resolution and coverage are improved, but data transmission burden increases
Solution Approach 1:
Large-area radiation conversion panels with high pixel counts are divided into multiple detection areas. Each area is processed independently, allowing the system to manage and transmit data from high-resolution panels more efficiently by handling segmented data streams rather than a single large data burden.
Solution Approach 2:
The system processes and transmits data from only the necessary detection areas rather than all areas of the radiation conversion panel. This partial action approach allows high-resolution imaging where needed while reducing overall data transmission requirements by excluding unnecessary data from areas not requiring full resolution.

AI summary
A radiation detector includes two radiation conversion panels for detecting radiation image information representing a radiation image of a subject. A signal combination judging circuit judges a combination of two serial signals representing the detected radiation image information. Based on the judged combination, an amplitude/phase modulator modulates the serial signal into an amplitude-modulated signal and modulates the phase of the amplitude-modulated signal according to the other serial signal, generating an amplitude/phase-modulated signal. The amplitude/phase-modulated signal is transmitted through an optical fiber to a console.
