Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computed tomography systems are inefficient in inspecting multiple targets simultaneously, as they require sequential positioning and scanning, increasing inspection time and reducing throughput.
Innovation Solution
A multi-target positioning unit is used to orient multiple targets simultaneously along a line of sight of an X-ray source, allowing for simultaneous X-ray direction and independent reorientation of targets during scanning to obtain attenuation information for producing computed tomography images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sequential positioning and scanning is used for multiple targets, then inspection accuracy is maintained, but inspection time increases and throughput decreases
Solution Approach 1:
The patent merges multiple target inspection operations into a single simultaneous scanning process. Multiple targets are positioned at different orientations on the rotating assembly, allowing the X-ray source and detector to scan all targets concurrently rather than sequentially, thereby reducing total inspection time while maintaining measurement precision through independent orientation control of each target.
Solution Approach 2:
The patent employs dynamic orientation control where each target can be independently reoriented to its optimal inspection angle during the scanning process. The rotating assembly allows continuous adjustment of target orientations, enabling dynamic optimization of inspection angles for each target while maintaining simultaneous scanning efficiency.
2Measurement precision
If sequential scanning of multiple targets is performed, then accurate CT images are obtained, but productivity decreases
Solution Approach 1:
The system combines multiple target inspections into a single integrated scanning operation. By mounting multiple targets on the rotating assembly with independent orientation mechanisms, the system acquires CT data for all targets simultaneously during one rotation cycle, dramatically increasing throughput while preserving image quality through maintained scanning accuracy for each target.
Solution Approach 2:
The rotating assembly enables continuous scanning action where the X-ray source and detector continuously rotate around all targets simultaneously. This continuous operation eliminates the stop-start nature of sequential scanning, maintaining constant data acquisition for all targets and maximizing productivity without compromising image quality.

AI summary
Computed tomography (CT) systems and related methods involving multi-target inspection are provided are provided. In this regard, a representative method includes: simultaneously directing X-rays toward multiple targets from an X-ray source; during the directing of the X-rays, independently reorienting the targets with respect to the X-ray source; and obtaining information corresponding to attenuation of the X-rays attributable to the multiple targets for producing computed tomography images of the targets.
