Radiation Imaging Offset Data Pre-acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiation imaging systems, the need to reacquire offset images for different imaging modes after a communication failure and mode transition can result in significant waiting time before imaging can resume, especially when the command communication control apparatus is restored.
Innovation Solution
A radiation imaging apparatus and method that includes a detection unit, communication unit, and controller, which operates in a normal imaging mode when communication is normal and switches to an abnormal imaging mode with offset data acquisition for a different mode during communication failures, allowing offset data to be pre-acquired without radiation irradiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system operates in emergency imaging mode during communication failure, then imaging can continue without command communication, but offset image data for other imaging modes becomes outdated and must be reacquired after communication is restored
Solution Approach 1:
The system pre-acquires offset image data for multiple imaging modes during normal communication operation. When communication fails and the system transitions to emergency imaging mode, the previously acquired offset data for other modes is already available in memory, eliminating the need for time-consuming reacquisition after communication is restored.
Solution Approach 2:
The system maintains a buffer of offset image data for multiple imaging modes before communication failure occurs. This cushioning approach ensures that when communication is restored, the system can immediately switch to any imaging mode using the pre-acquired offset data without waiting for reacquisition.
2Measurement precision
If offset image data is reacquired after communication is restored from emergency imaging mode, then imaging accuracy is maintained, but significant waiting time occurs before imaging can resume
Solution Approach 1:
Offset image data for multiple imaging modes is acquired in advance during normal communication operation. When communication is restored after emergency mode, the system can immediately use the pre-acquired offset data to maintain imaging accuracy without requiring time-consuming reacquisition procedures.
Solution Approach 2:
The system maintains continuous availability of offset image data for multiple imaging modes by acquiring them during normal operation. This ensures that when communication is restored, imaging can resume immediately in any mode without interruption or waiting time, maintaining both accuracy and productivity.
3Speed
If the system maintains offset image data for multiple imaging modes during normal operation, then switching between modes is rapid, but memory requirements and data management complexity increase
Solution Approach 1:
The offset image data storage system is designed to handle multiple imaging modes universally. A single memory structure stores offset data for all imaging modes, and the system can switch between modes by selecting from this universal storage, achieving rapid switching without proportionally increasing overall system complexity.
Solution Approach 2:
The system manages multiple imaging modes by changing parameters such as accumulation time, binning number, and sensitivity settings while using a unified offset data storage structure. This allows rapid mode switching through parameter adjustments rather than requiring separate complex storage systems for each mode.

Function Achieved in This Case
This approach reduces waiting time by enabling quick resumption of imaging operations when communication is restored by pre-acquiring offset data for alternative imaging modes during abnormal communication states.

AI summary
A radiation imaging apparatus comprising a detection unit in which a plurality of pixels are arranged, a communication unit configured to receive a control signal including an imaging mode for acquiring a radiation image by the detection unit and a controller is provided. The controller operates the detection unit in an imaging mode corresponding to the control signal if an imaging instruction is received in a first state in which a state of communication is normal, operates the detection unit in an abnormal imaging mode set in advance if the imaging instruction is received in a second state in which the state of communication is not normal, and operates the detection unit so as to acquire offset image data for an imaging mode different from the abnormal imaging mode while radiation irradiation is not performed in the second state.
