Radiation Detector Power State Control via Console Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat panel detectors (FPDs) in radiation image radiographing systems do not automatically adjust their power state based on the operation status of the console, leading to increased operational complexity and the risk of unnecessary radiation exposure during urgent radiography.
Innovation Solution
A radiation image radiographing system that includes a radiation image detector with a power supplying section capable of automatically controlling its power state based on the operation status of the associated console, featuring three power states: capable of radiography, waiting radiography, and preparing waiting, to optimize power consumption and reduce operational errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the radiation image detector is always kept in a ready state for radiography, then the operational speed and responsiveness are improved, but the power consumption increases and operational complexity increases
Solution Approach 1:
The radiation image detector dynamically adjusts its operational state based on the console's status. When the console is in operation, the detector transitions to a ready state for quick radiography. When the console is halted, the detector enters a low-power state. This dynamic adaptation resolves the contradiction by making the system responsive only when needed.
Solution Approach 2:
The system implements feedback through the associating section that continuously monitors the console's operation status and automatically adjusts the detector's power state accordingly. This feedback mechanism eliminates the need for manual intervention and ensures the detector is ready precisely when the console requires it, maintaining operational speed while reducing unnecessary power consumption.
2Use of energy by moving object
If manual start-up commands are required for the radiation image detector, then power consumption is reduced when not in use, but operational complexity increases and the risk of errors increases
Solution Approach 1:
The radiation image detector performs self-service by automatically detecting the console's operation status through the associating section and adjusting its own power state without requiring manual commands. This self-service capability eliminates operational complexity and reduces the risk of human error while maintaining appropriate power consumption levels.
Solution Approach 2:
The automatic feedback mechanism monitors the console's operational state and triggers appropriate power state transitions in the detector. This eliminates the need for manual start-up commands, reducing operational complexity and preventing errors such as using an unstarted detector or unnecessary radiation exposure.
3Extent of automation
If the radiation image detector is associated with the console, then operational automation is improved, but device complexity increases
Solution Approach 1:
The associating section serves multiple functions: it detects the console's operation status, determines appropriate power states, and controls the detector's operational mode. By consolidating these functions into a single component, the system achieves high automation without proportionally increasing overall device complexity.
