Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image acquisition systems for human anatomical shapes are prone to inaccuracies due to subject movement during scanning, which complicates three-dimensional reconstruction, especially when multiple angles and positions are required for precise anatomical landmark and measurement derivation.
Innovation Solution
A system with fixed, integrated optical sensors anchored to a support structure at preset heights and angles, allowing synchronized image acquisition without subject or sensor movement, ensuring a sufficient number of images are captured for accurate three-dimensional digital reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotating platform or moving sensor system is used to capture images from multiple angles, then comprehensive anatomical data can be acquired, but subject movement during scanning increases and reconstruction accuracy deteriorates
Solution Approach 1:
Instead of moving the sensors or the subject during scanning, the patent inverts the approach by using multiple fixed sensor arrays positioned at different locations around the subject. Each array captures images from its fixed position, eliminating movement-related errors while still achieving comprehensive multi-angle coverage through the distributed fixed sensors.
Solution Approach 2:
The patent divides the imaging system into multiple independent fixed sensor arrays positioned at different locations and angles around the subject. Each array independently captures images from its specific viewpoint, and the results are integrated during reconstruction. This segmentation allows comprehensive data acquisition without requiring any single sensor to move.
2Measurement precision
If multiple sensors are positioned at different heights and angles to capture complete anatomical shapes, then reconstruction fidelity improves, but system complexity increases
Solution Approach 1:
The patent employs multiple fixed sensor arrays that serve universal functions: each array can capture images of different body regions depending on its position, and all arrays work together to provide comprehensive coverage. This multi-functionality reduces the need for specialized moving mechanisms while achieving high reconstruction fidelity through the coordinated operation of fixed sensors at various heights and angles.
3Measurement precision
If the subject remains completely still during scanning, then reconstruction accuracy is maximized, but the scanning time increases
Solution Approach 1:
The patent performs preliminary positioning of multiple fixed sensor arrays around the subject before scanning begins. Each sensor array is pre-positioned at optimal locations and angles to capture specific anatomical regions. This preliminary setup eliminates the need for dynamic adjustment during scanning, allowing the subject to remain still while comprehensive data is captured simultaneously by all fixed sensors.
Solution Approach 2:
The patent achieves continuous image capture across all body regions by having multiple fixed sensor arrays operate simultaneously. Rather than sequentially scanning different areas with a single moving sensor, all sensors capture images at the same time, maintaining continuous useful action throughout the scanning process and reducing total scan time while keeping the subject stationary.
