Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical movement of the x-ray source and detector is used to adjust the viewing direction, then the desired configuration can be achieved, but inaccuracies are introduced due to movement
Solution Approach 1:
The patent replaces physical mechanical movement of the x-ray source and detector with a computational approach. Configuration data is calculated using optimization algorithms that determine the required positions and collimator settings based on the target line and fluoroscopic image, eliminating the need for physical repositioning and associated inaccuracies.
Solution Approach 2:
The patent creates a virtual model or representation of the desired configuration through calculation rather than physically moving components. The configuration data represents a computational copy or equivalent of the physical arrangement that would be needed, allowing precise determination without physical disturbance.
2Manufacturing precision
If the medical imaging system configuration is adjusted to align the central beam with the target line, then optimal imaging is achieved, but the system complexity increases
Solution Approach 1:
The system performs self-determination of its configuration by automatically calculating the required positions and collimator settings based on the fluoroscopic image and target line. The optimization algorithm enables the system to self-adjust without requiring complex manual intervention or additional hardware components.
Solution Approach 2:
The patent determines configuration by calculating optimal values for system parameters (x-ray source position, detector position, collimator settings) rather than physically adjusting components. This computational parameter determination simplifies the adjustment process while achieving precise beam alignment.
3Adaptability or versatility
If collimator settings are adjusted to change the central beam direction, then the viewing direction can be modified, but the device complexity increases
Solution Approach 1:
The patent calculates the optimal collimator settings in advance as part of the configuration determination process. By pre-determining the required collimator configuration based on the target line and imaging requirements, the system avoids complex real-time adjustments and simplifies the operation.
Solution Approach 2:
The system uses the fluoroscopic image as feedback to determine the appropriate collimator settings. The optimization algorithm processes the image information and target line data to calculate the configuration that achieves the desired viewing direction, creating a closed-loop system that simplifies adjustment through intelligent calculation.

AI summary
This document relates to determining the configuration of a medical imaging system, in particular a configuration which defines a desired viewing direction of the medical imaging system onto a patient. First, a fluoroscopic image of at least a part of a patient is captured using the medical imaging system and the target central beam is set in the fluoroscopic image. Then a target line in space is determined which, when projected into the fluoroscopic image, coincides with the set target central beam. Then the configuration of the medical imaging system is determined such that the central beam of the medical imaging system coincides with the target line in space.
