X-ray Source Suspension Speed Control for Precision Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray imaging systems face challenges in efficiently moving the X-ray source to target positions, requiring improved control mechanisms for precise positioning during scans.
Innovation Solution
A system comprising an X-ray imaging device with a suspension device suspended from a rail, a control device, and a processor that determines the speed of the suspension device at reference points along the rail, actuating the control device to move the X-ray source to target positions when the speed falls below a threshold, allowing for automatic or manual movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suspension device is moved manually to target positions, then the ease of operation is improved, but the productivity and positioning precision deteriorate
Solution Approach 1:
The system dynamically switches between manual and automatic movement modes based on operational needs. The suspension device can operate in manual mode for flexibility and in automatic mode for high-speed, precise positioning, allowing the system to adapt its control strategy to different operational phases and requirements
Solution Approach 2:
The system continuously monitors the speed of the suspension device at reference points and uses this feedback to determine when to activate automatic movement control. When the speed falls below a threshold, the system automatically actuates the control device to move the suspension device to the target position, creating a closed-loop control system that improves both productivity and positioning precision
2Productivity
If the suspension device moves at high speed, then the productivity is improved, but the manufacturing precision and positioning accuracy deteriorate
Solution Approach 1:
The system uses periodic monitoring of the suspension device speed at reference points along the rail. By checking the speed at intervals and comparing it to threshold values, the system can determine the optimal moment to switch from high-speed travel to precision positioning, enabling periodic acceleration and deceleration cycles that maintain high productivity while ensuring accurate positioning
Solution Approach 2:
The system performs preliminary monitoring of the suspension device speed before reaching the target position. By detecting when the speed falls below the threshold at reference points, the system prepares and activates the automatic control mechanism in advance, ensuring that the suspension device is ready for precise positioning before it arrives at the target location

AI summary
A method for controlling the movement of an X-ray source via a suspension device includes obtaining, during a movement of the suspension device along the rail, a first speed of the suspension device at the first reference point. The first reference point may correspond to a first target position. The method may also include determining whether the first speed of the suspension device at the first reference point is less than a threshold speed. In response to a result of the determination that the first speed of the suspension device at the first reference point is less than the threshold speed, the method may further include actuating a control device to move the suspension device to the first target position.
