A digital radiography system with modules for X-ray generation, acquisition, support, and control, which includes a control module that uses positional information and artificial potential field methods to adjust the motion of components, detect obstacles, and select between vertical, horizontal, or free-style configurations based on the presence of imaging targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the X-ray generation and acquisition modules are positioned to optimize imaging quality, then the imaging quality and detection accuracy are improved, but the risk of collision between modules and with imaging targets increases
Solution Approach 1:
The sensing unit detects obstacles and the control module pre-adjusts the motion of moving components before collision occurs. The system proactively identifies potential collision risks and takes preventive action by modifying motion parameters, rather than reacting after collision happens.
Solution Approach 2:
The sensing unit continuously monitors the position of moving components and obstacles, providing real-time feedback to the control module. The control module processes this feedback and dynamically adjusts motion parameters to maintain safe distances while optimizing imaging quality.
2Adaptability or versatility
If the system uses multiple configurations (vertical, horizontal, free-style) to adapt to different imaging targets, then the adaptability and versatility are improved, but the device complexity increases
Solution Approach 1:
The system integrates multiple configurations (vertical, horizontal, free-style) into a single unified platform. The control module automatically selects and switches between configurations based on the imaging target and clinical requirements, eliminating the need for separate dedicated systems for each configuration type.
Solution Approach 2:
The system employs dynamically adjustable components that can change their position and orientation based on the selected configuration mode. The control module dynamically reconfigures the spatial arrangement of X-ray generation and acquisition modules to match the required imaging scenario.
3Reliability
If the control module continuously monitors and adjusts motion parameters to prevent collision, then the safety and reliability are improved, but the control system complexity and processing requirements increase
Solution Approach 1:
The control module pre-establishes safety thresholds and motion constraints based on the detected configuration and obstacle positions. By setting these parameters in advance, the system reduces the computational burden during real-time operation while maintaining safety.
Solution Approach 2:
The sensing unit and control module work together in an autonomous manner where the sensing unit automatically detects obstacles and the control module independently processes the information and adjusts motion parameters without requiring external intervention, simplifying the overall control architecture.
