Integrator Switch Decoupling for X-Ray Panel Crosstalk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiological imaging systems using digital X-ray panels often experience image artifacts due to charge dumping and crosstalk between components, which are not effectively regulated by existing circuitry, leading to suboptimal image quality.
Innovation Solution
A method and system where a switch is used to decouple the integrator from the digital X-ray panel prior to an integrator event or fault detection, preventing charge dumping and crosstalk by opening the interface switch between the integrator and the panel, thereby regulating signal acquisition and reducing image artifacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the integrator continuously integrates the analog input signal from the digital X-ray panel, then signal acquisition is maintained, but charge dumping and crosstalk occur resulting in image artifacts
Solution Approach 1:
The switch opens in advance before the integrator event occurs, preventing charge dumping and crosstalk before they can affect the integration process. This preliminary decoupling action eliminates the harmful effects while allowing continuous operation.
Solution Approach 2:
The switch acts as an intermediary element between the integrator and the digital X-ray panel, controlling the coupling state to prevent harmful charge dumping while allowing normal signal integration during operational phases.
2Object-affected harmful factors
If the switch opens to decouple the integrator from the digital X-ray panel, then charge dumping and crosstalk are prevented, but signal acquisition is interrupted
Solution Approach 1:
The switch operates periodically, opening briefly before integrator events to prevent charge dumping, then closing to resume signal acquisition. This periodic coupling and decoupling maintains continuous operation while preventing harmful effects during critical moments.
Solution Approach 2:
The switch opens in advance before the integrator event, preventing charge dumping before it can occur, then closes afterward to resume normal signal acquisition, ensuring minimal interruption to productivity.
3Device complexity
If the integrator remains coupled to the digital X-ray panel during faults, then system complexity is reduced, but fault propagation and additional image artifacts occur
Solution Approach 1:
The switch serves as a protective intermediary that can be opened upon detecting a fault in the digital X-ray panel, isolating the integrator from the faulty component and preventing fault propagation, while maintaining a simple overall coupling structure.
Solution Approach 2:
The coupling between the integrator and digital X-ray panel is segmented by the switch, allowing independent control of the connection state. This segmentation enables fault isolation without requiring complete system redesign, maintaining simplicity while improving reliability.
