Solution Overview
Problem
In fluoroscopy, the anatomical region being imaged often changes during the examination, necessitating a general image processing that may not be optimal for specific regions, leading to suboptimal imaging parameters.
Innovation Solution
A device and method that provide position and orientation data of both the object and imaging unit to determine the region to be imaged, allowing for the automatic selection and adjustment of imaging parameters, such as image processing and irradiation settings, based on real-time data from anatomical models and landmarks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a general image processing is applied to images of different anatomical regions in fluoroscopy, then the imaging system can handle changing anatomical regions, but the image processing becomes non-optimal for particular anatomical regions
Solution Approach 1:
The patent segments the anatomical regions by detecting anatomical landmarks and dividing the imaging space into different regions (e.g., head, thorax, abdomen) based on the position of the imaging unit and identified landmarks. This allows different image processing parameters to be applied to different segments, resolving the contradiction between handling changing regions and maintaining optimal processing quality.
Solution Approach 2:
The patent applies local quality by setting different image processing parameters (such as contrast, brightness, filtering) specifically for each detected anatomical region rather than using uniform processing across the entire field of view. This ensures optimal image quality for each particular anatomical region while maintaining adaptability to changing regions during the examination.
2Manufacturing precision
If manual adjustment of image processing parameters is performed for each anatomical region, then optimal image processing can be achieved, but the complexity and time required increases
Solution Approach 1:
The patent implements self-service by enabling the system to automatically detect anatomical landmarks, identify the current anatomical region, and select appropriate image processing parameters without requiring manual intervention from the operator. The system serves itself by autonomously adapting to changing anatomical regions, thereby maintaining optimal image quality while reducing operational complexity.
Solution Approach 2:
The patent uses feedback mechanisms where the system continuously monitors the position of the imaging unit and detected anatomical landmarks, then automatically adjusts image processing parameters based on this feedback. This closed-loop control eliminates the need for manual parameter adjustment while maintaining optimal processing quality for each anatomical region.
3Extent of automation
If automatic detection of anatomical regions is implemented, then optimal imaging parameters can be selected automatically, but the measurement and detection complexity increases
Solution Approach 1:
The patent introduces intermediary elements such as fiducial markers or reference objects that facilitate the automatic detection of anatomical landmarks. These intermediaries provide easily detectable features that help the system identify anatomical regions and adjust imaging parameters automatically, reducing the complexity of direct anatomical landmark detection while maintaining high automation levels.
