Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During robot-assisted medical interventions in the vascular system, existing X-ray devices require time-consuming manual adjustments to focus on specific objects of interest, which can be inefficient and may expose patients to unnecessary X-ray doses due to non-specific image settings.
Innovation Solution
A method and system for automatically setting X-ray device parameters based on selection criteria, such as image analysis and eye tracking data, to highlight the relevant object in X-ray images, reducing manual effort and optimizing image quality and radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of X-ray recording parameters is used to focus on specific objects, then image quality for the object of interest can be optimized, but the procedure becomes time-consuming and increases patient radiation exposure
Solution Approach 1:
The system automatically selects the object of interest and adjusts recording parameters without requiring manual operator intervention. The robotic system itself provides the service of optimizing image parameters by autonomously identifying relevant objects and configuring the X-ray device accordingly, eliminating the time-consuming manual adjustment process while maintaining image quality
Solution Approach 2:
The system uses selection criteria to continuously monitor and identify objects of interest, then provides feedback to automatically adjust recording parameters. This closed-loop approach ensures that the X-ray device adapts to the current surgical situation in real-time, optimizing image quality for the relevant object without manual intervention and reducing overall procedure time
2Measurement precision
If manual adjustment of X-ray recording parameters is used to focus on specific objects, then image quality for the object of interest can be optimized, but patient radiation exposure increases due to non-specific image settings
Solution Approach 1:
The system autonomously optimizes recording parameters for the specific object of interest without requiring broad-area imaging. By automatically identifying the relevant object and configuring the X-ray device to focus only on that object, the system minimizes the irradiated area and reduces patient radiation exposure while maintaining high image quality for the target object
Solution Approach 2:
The system applies different recording parameters specifically to the object of interest rather than uniformly across the entire field of view. By localizing the high-quality imaging to only the relevant object and using automatic selection criteria, the system reduces radiation exposure to surrounding areas while ensuring optimal image quality where needed
3Object-affected harmful factors
If manual selection of region of interest is performed, then X-ray beam can be limited to reduce radiation, but the process is time-consuming and may not accurately identify the most relevant object
Solution Approach 1:
The system automatically performs the selection of the region of interest without manual operator input. The robotic system autonomously identifies the most relevant object using selection criteria and configures the X-ray beam accordingly, eliminating the time-consuming manual selection process while ensuring accurate identification of the target object and minimizing radiation exposure
Solution Approach 2:
The manual mechanical process of adjusting diaphragms and selecting regions of interest is replaced by an automated electronic control system. The system uses selection criteria and automatic object recognition to determine the region of interest, then electronically controls the diaphragm settings, replacing the manual mechanical adjustment process with an automated electronic system that is both faster and more accurate
4Productivity
If automatic general setting of recording parameters is used, then procedure time is reduced, but the settings are not specific enough for the object of interest
Solution Approach 1:
The system uses dynamic selection criteria that automatically adapt to the current surgical situation and identify the most relevant object. Rather than using static general settings, the system continuously evaluates objects against multiple criteria and dynamically adjusts recording parameters to match the specific object of interest, maintaining both efficiency and image quality specificity
Solution Approach 2:
The system pre-configures multiple selection criteria that evaluate objects based on their surgical relevance. By having these criteria prepared in advance and automatically applying them to identify the object of interest, the system can quickly determine the appropriate specific settings without manual intervention, achieving both procedural efficiency and image quality specificity

AI summary
A method for actuating an X-ray device during robot-assisted navigation of at least two objects introduced into a body, such as a hollow organ, of a patient by at least one robotic system, includes providing a first selection criterion for selecting one of the objects, and providing a second selection criterion for selecting one of the objects. One of the at least two objects is selected based on the first selection criterion and the second selection criterion, and recording parameters of the X-ray device are automatically set, such that the selected object in an X-ray image to be recorded is highlighted compared to the at least one other object. The selected object may be highlighted with respect to image quality, image flavor, positioning on the X-ray image, and/or a collimator setting of a collimator of the X-ray device. An X-ray image is recorded with the set recording parameters.
