Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple x-ray imaging systems are used to detect the marker device, then the accuracy of detecting the marker device is improved, but the device complexity increases
Solution Approach 1:
The system is divided into multiple independent x-ray imaging systems, each capable of detecting the marker device. By segmenting the detection function across multiple systems, the patent achieves more accurate determination of marker device configuration through data fusion from multiple sources, while each individual system remains relatively simple in structure.
2Loss of time
If the configuration of the medical x-ray imaging system is determined manually, then the device complexity is reduced, but the time consumption increases
Solution Approach 1:
The system automatically determines its own configuration parameters by analyzing images of the marker device detected by the x-ray imaging systems. The configuration determination is performed autonomously without requiring manual intervention, as the system self-calibrates by detecting known marker device positions and calculating the corresponding imaging system parameters.
3Productivity
If the configuration determination is performed automatically, then the time consumption is reduced, but the device complexity increases
Solution Approach 1:
The system uses feedback from detected marker device images to automatically adjust and determine configuration parameters. The detected marker positions provide feedback information that is processed to calculate optimal configuration settings, enabling automatic adaptation without requiring complex external calibration equipment.

AI summary
This document relates to technologies of determining a configuration of a medical imaging system comprising an x-ray source and an x-ray detector mounted on a gantry and an x-ray source collimator for shaping the x-ray beam emitted by the x-ray source, wherein at least one of the x-ray source and the x-ray detector is movable along the gantry. The configuration of the medical imaging system comprises the position of the x-ray source, the position of the x-ray detector and the settings of the x-ray source collimator and is to be used for capturing a marker image, wherein the position of the marker device can be calculated using the marker image.
