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 emit x-rays simultaneously or sequentially, allowing for the acquisition of image data from different positions, enabling larger imaging volumes by positioning sources angularly and moving them in patterns such as circular, helical, or spiral motions relative to the subject.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a single source and detector configuration is used, then the device complexity is reduced, but the imaging volume is limited and larger equipment is required for larger objects
Solution Approach 1:
The imaging system divides the source into multiple discrete sources arranged in an array, where each source can be independently controlled to emit x-rays. This segmentation allows the system to image larger volumes by activating only the necessary subset of sources, rather than requiring a single large source-detector configuration.
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 keeping individual source and detector elements compact.
2Volume of moving object
If a larger source and detector are used to image larger objects, then the imaging volume increases, but the device complexity and size increase
Solution Approach 1:
Instead of using one large source and detector, the system segments them into multiple smaller units arranged in arrays. This allows the imaging volume to be expanded by activating more segments rather than increasing the size of individual components.
Solution Approach 2:
Multiple small source elements and detector elements are nested within a compact housing structure, allowing the system to achieve large imaging volume capability while maintaining a relatively compact overall equipment size.
3Volume of moving object
If multiple sources are used to image larger volumes, then the imaging volume increases, but the data acquisition and image reconstruction complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-planning which subset of sources to activate and which detector elements to use based on the desired imaging volume. This preliminary configuration planning simplifies the subsequent data acquisition and reconstruction processes compared to handling all possible source combinations.
Solution Approach 2:
Instead of using all available sources simultaneously, the system activates only the necessary partial subset of sources required for the specific imaging task. This partial action approach reduces the complexity of data acquisition and image reconstruction while still achieving the required imaging volume.

Function Achieved in This Case
This approach allows for the imaging of larger volumes with a smaller source and detector configuration, enhancing data acquisition efficiency and image reconstruction capabilities, particularly in medical procedures like stent placement and deep brain stimulation.
Implementation Method 1
The plurality of sources may be individually powered to emit a signal, such as x-rays, from each of the individual sources
