Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radiation imaging techniques, such as two-stage X-ray Computed Tomography (CT) and X-ray Diffraction (XRD) detection systems, are bulky and inefficient due to the use of independent radiation sources, leading to low detection efficiency and difficulty in achieving high imaging quality.
Innovation Solution
A detection system utilizing a distributed radiation source with multiple focus points, grouped to share a single set of radiation sources for simultaneous CT and XRD detection, and a primary collimator to direct rays to corresponding XRD detectors, reducing crosstalk and angular deviation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a two-stage detection system with independent radiation sources is used for CT and XRD detection, then detection accuracy is improved, but system size increases and detection efficiency decreases
Solution Approach 1:
The patent combines CT and XRD detection systems into a unified detection system that shares a single radiation source. The radiation source is configured with multiple focus points that can be selectively activated, allowing both CT and XRD detection functions to be performed using the same physical hardware, thereby reducing system size and improving detection efficiency while maintaining detection accuracy through the specialized detection paths for each modality
2Reliability
If a two-stage detection system with independent radiation sources is used for CT and XRD detection, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges two independent detection systems into one unified system by sharing the radiation source. The radiation source incorporates multiple focus points that can be selectively activated for different detection modes, reducing the number of independent components needed while maintaining the specialized detection paths required for accurate CT and XRD detection
Solution Approach 2:
The radiation source is designed with multi-functionality, serving both CT and XRD detection purposes. By configuring the radiation source with multiple focus points and enabling selective activation, a single component performs the functions that previously required two separate radiation sources, thereby reducing device complexity
3Measurement precision
If a distributed radiation source with grouped focus points is used, then crosstalk is reduced and imaging quality is improved, but device complexity increases
Solution Approach 1:
The patent segments the radiation source into multiple focus points that are divided into groups, and correspondingly segments the detectors into matching groups. This segmentation allows selective activation of specific focus points and their corresponding detectors, reducing crosstalk between different detection paths while maintaining comprehensive coverage for high-quality imaging
Solution Approach 2:
The patent applies local quality by assigning specific groups of focus points and detectors to handle specific detection tasks or regions. This localized assignment ensures that each detector group receives signals primarily from its corresponding focus point group, reducing crosstalk and improving measurement precision while the overall system maintains comprehensive detection capability
