X-Ray Imaging Workflow Control for Gantry Alignment Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current imaging systems lack effective mechanisms to ensure that radiation emitters and detectors are properly aligned relative to the subject before imaging, leading to potential operational errors and suboptimal image acquisition.
Innovation Solution
The imaging system includes a control system that identifies and corrects the alignment of radiation emitters and detectors relative to the subject, notifying users of misalignments and restricting operation until proper alignment is achieved, ensuring both the radiation emitter and detector are at predetermined start angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the imaging system operates without alignment verification, then the operation speed is improved, but the image acquisition quality deteriorates
Solution Approach 1:
The control system performs alignment verification of the radiation emitter and detector relative to the subject before imaging operation begins. The system identifies positions and notifies users of misalignments in advance, allowing correction before actual image acquisition, thus ensuring alignment precision without significantly delaying operation.
2Manufacturing precision
If the control system verifies alignment before imaging, then the image quality is improved, but the operation time increases
Solution Approach 1:
The control system continuously monitors the positions of the radiation emitter and detector, providing real-time feedback to users about alignment status. When misalignment is detected, the system notifies users and guides correction, allowing for efficient alignment adjustment without excessive time loss.
3Reliability
If the system restricts operation until proper alignment is achieved, then the reliability is improved, but the productivity decreases
Solution Approach 1:
The system performs alignment verification as a preliminary step before allowing imaging operation. By ensuring proper alignment in advance through position identification and user notification, the system prevents operational errors and rework, thereby maintaining high reliability while minimizing impact on overall productivity.
