Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing x-ray imaging technologies struggle to simultaneously optimize the visibility of multiple objects with different material properties, leading to sub-optimal representation in output images.
Innovation Solution
The method involves alternating between multiple sets of recording parameters to capture x-ray images, allowing for enhanced visibility of objects with different material properties by generating merged output images that combine data from different parameter settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single set of recording parameters is selected to optimize visibility of one object, then visibility of that specific object is improved, but visibility of other objects with different material properties deteriorates
Solution Approach 1:
The patent merges multiple x-ray images acquired with different recording parameter sets into a single composite output image. Each parameter set optimizes visibility for specific objects, and the merging process combines these optimized views to achieve simultaneous visibility of multiple objects with different material properties that would be invisible or poorly visible in any single parameter set.
Solution Approach 2:
The patent systematically varies recording parameters (such as tube voltage, pulse width, and filtration) across multiple acquisition cycles. By changing parameters between acquisitions and combining the results, the system adapts to capture different object types optimally without requiring manual reconfiguration for each object.
2Measurement precision
If manual selection of recording parameters is used to match a specific object class, then visibility of objects in that class is improved, but visibility of other object classes deteriorates or is lost
Solution Approach 1:
The system performs automatic detection and classification of objects in the recording area, then autonomously selects and switches between appropriate recording parameter sets without requiring manual user intervention. The system serves itself by identifying what needs to be imaged and configuring the optimal parameters for capturing multiple object types simultaneously.
Solution Approach 2:
The system dynamically adapts recording parameters based on real-time detection of objects in the recording area. Rather than static manual configuration, the parameter selection changes automatically according to the detected object composition, enabling the system to respond to varying imaging needs during the procedure.
3Measurement precision
If multiple sets of recording parameters are used to capture different objects, then visibility of all objects is improved, but system complexity increases
Solution Approach 1:
The system employs periodic switching between different recording parameter sets in a predetermined sequence during repeated acquisitions. This structured periodic alternation simplifies control compared to arbitrary parameter changes, as the system cycles through predefined parameter configurations optimized for different object types, making the complexity manageable through regular patterns.
4Measurement precision
If fast parameter switching is implemented to capture multiple objects, then visibility of all objects is improved, but loss of time in image processing increases
Solution Approach 1:
The system performs preliminary detection and classification of objects in the recording area before the actual imaging sequence. Based on this advance knowledge, the optimal recording parameter sets and their switching sequence are predetermined. This preliminary preparation enables fast parameter switching during acquisition without requiring complex real-time processing decisions, reducing overall processing time.

AI summary
A method for operating an x-ray device includes: recording a series of x-ray images of a recording area, (e.g., for monitoring the recording area); and determining a series of output images to be output from the x-ray images. When the x-ray images are recorded, there is a repeated change between at least two sets of recording parameters that leads to the different representation of at least two different objects of the recording area in the x-ray images. Further, the output images are determined in each case at least from one set of x-ray images that includes x-ray images recorded with at least two of the at least two sets of recording parameters.
