Multiple X-ray Source Array for Large Volume Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging systems are limited to a single source and detector, restricting the volume that can be imaged and requiring larger equipment for larger objects, which hinders efficient data acquisition and image reconstruction.
Innovation Solution
A multiple source imaging system is developed, where multiple sources spaced apart emit x-rays simultaneously or sequentially to acquire image data from different positions, allowing for a larger imaging volume with a smaller detector, and the sources can be moved in various patterns relative to the subject to enhance data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a single source and detector are used, then the device complexity is reduced, but the imaging volume is limited and requires larger equipment for larger objects
Solution Approach 1:
The imaging system divides the radiation source into multiple discrete sources arranged in an array, where each source can be independently controlled. This segmentation allows the system to image larger volumes by utilizing multiple sources simultaneously or sequentially, rather than relying on a single large source-detector assembly.
Solution Approach 2:
The patent transitions from a single-point source to a multi-point source array, adding spatial dimensionality to the source configuration. This dimensional expansion enables coverage of larger imaging volumes while maintaining a compact detector size, effectively solving the volume-complexity tradeoff.
2Volume of moving object
If a larger source and detector are used to image larger objects, then the imaging volume increases, but the device size and complexity increase
Solution Approach 1:
Instead of using one large detector, the system uses multiple small sources that can be selectively activated. This segmentation allows the imaging volume to be expanded by adding more sources rather than enlarging the detector, maintaining a compact detector footprint while achieving larger volume coverage.
Solution Approach 2:
The detector maintains a standard size but gains universal applicability by working with different configurations of multiple sources. The same detector can image various volumes by activating different subsets of sources, providing multi-functionality without requiring multiple detector sizes.
3Productivity
If multiple sources are used to image larger volumes, then the imaging volume and data acquisition efficiency improve, but the device complexity increases
Solution Approach 1:
The source array is segmented into independently controllable units, allowing selective activation based on the imaging requirements. This segmentation enables efficient data acquisition by activating only the necessary sources for a given imaging task, improving productivity while managing complexity through modular control.
Solution Approach 2:
The system can activate multiple sources in sequential periods or simultaneously, allowing flexible data acquisition strategies. This periodic or simultaneous activation of multiple sources improves imaging efficiency by collecting data from multiple angles or positions without requiring physical movement of the entire system.
