Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
X-ray Talbot imaging systems face noise and reconstruction issues due to environmental changes affecting the grating structure and installation environment, which are not effectively managed by current technologies, especially when imaging objects under varying temperature and humidity conditions.
Innovation Solution
An X-ray imaging system with an object housing that maintains an independent environmental condition, allowing the object to be imaged under different conditions without altering the installation environment of the X-ray Talbot imaging apparatus, using a Talbot-Lau interferometer with a source grating, first grating, and second grating, and an X-ray detector, and employing fringe scanning and Fourier transform techniques to capture high-resolution reconstruction images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the object is imaged under varying environmental conditions (temperature, humidity), then the ability to observe internal mechanism changes under different environments is improved, but noise and reconstruction errors increase due to grating deformation
Solution Approach 1:
The system divides the imaging space into two independent environmental zones: the object chamber where environmental conditions can vary, and the grating chamber where conditions are controlled and stable. This segmentation allows the object to experience different temperatures and humidities while the gratings remain in a controlled environment, preventing grating deformation and maintaining measurement precision.
Solution Approach 2:
The patent introduces an environmental isolation mechanism (housing with separate chambers) that acts as an intermediary between the object and the grating system. This intermediary structure allows environmental conditions to be independently controlled for each component, preventing direct transmission of environmental variations from the object to the sensitive grating structures.
2Adaptability or versatility
If the installation environment of the X-ray Talbot imaging apparatus is changed to match object environmental conditions, then the object can be imaged in its natural environment, but the grating structure deforms causing noise and reconstruction errors
Solution Approach 1:
The housing is divided into separate chambers: an object chamber that can be subjected to varying environmental conditions (temperature, humidity) and a grating chamber that maintains stable, controlled conditions. This spatial segmentation allows the system to image objects under special environmental conditions while protecting the sensitive grating structure from deformation and maintaining system reliability.
Solution Approach 2:
Different environmental conditions are applied to different parts of the system: the object chamber experiences the required special environmental conditions (high temperature, high humidity, etc.) while the grating chamber maintains stable, controlled conditions. This local differentiation of environmental quality allows simultaneous achievement of imaging adaptability and system stability.
3Measurement precision
If environmental control is applied to the entire imaging system, then grating deformation is prevented, but the ability to image objects under special environmental conditions is lost
Solution Approach 1:
The system employs spatial segmentation with separate environmental control for different chambers. The grating chamber maintains controlled, stable environmental conditions to prevent grating deformation and ensure high-quality reconstruction images, while the object chamber can be subjected to varying environmental conditions, enabling observation of objects under different environments without compromising either measurement precision or adaptability.
