Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray radiography devices are bulky and prone to image distortion due to the large size and configuration of X-ray generators and detectors, which increases manufacturing costs and limits their application in smaller targets.
Innovation Solution
The X-ray radiography device features a matrix arrangement of X-ray emitting elements, such as carbon nanotube cathodes, emitting X-rays in a pixel matrix configuration, and a corresponding matrix of detecting elements that map one-to-one or one-to-many to the emitting elements, allowing for focused X-ray transmission and detection without the need for extensive physical movement of the source or detector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional X-ray generators and detectors are used with large size configuration, then the device can achieve basic imaging function, but the device size becomes bulky and manufacturing cost increases
Solution Approach 1:
The patent divides the X-ray source and detector into multiple discrete elements arranged in matrix arrays. Each element can be independently controlled and positioned, allowing the system to achieve high-resolution imaging through precise spatial arrangement rather than requiring large overall device dimensions. The segmented structure enables compact configuration while maintaining imaging capability.
Solution Approach 2:
The patent transitions from conventional single-point or single-line X-ray sources to two-dimensional matrix arrays of X-ray emitting elements. This dimensional expansion allows parallel imaging from multiple positions simultaneously, achieving high resolution without increasing the physical footprint of the device in any single dimension.
2Measurement precision
If conventional single-point X-ray sources are used, then the device structure is simple, but image distortion occurs due to large source-to-detector distance
Solution Approach 1:
By segmenting the X-ray source into multiple elements distributed across a matrix, the patent reduces the effective source-to-detector distance for each individual element. This segmentation allows each element to contribute to the image with minimal distortion, and the combined data from all elements produces a high-accuracy reconstructed image without requiring a complex mechanical positioning system.
Solution Approach 2:
The patent replaces the need for mechanical movement and positioning of a single large source with a static matrix array of multiple small elements. Instead of moving a single source to multiple positions, the system uses multiple fixed sources that can be activated selectively, eliminating complex mechanical driving mechanisms while achieving the same imaging geometry.
3Measurement precision
If multiple X-ray sources are arranged in matrix configuration, then high-resolution imaging is achieved, but the driving mechanism becomes more complex
Solution Approach 1:
The patent employs a universal control architecture where all X-ray emitting elements and detecting elements in the matrix are managed through a common addressing and control system. Each element can be independently activated or read out through standardized control signals, allowing the system to handle multiple elements with a single type of control mechanism rather than requiring specialized control circuitry for each element.
