Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a movable source and detector are used to acquire multiple projections from different perspectives, then three-dimensional image quality and anatomical visualization are improved, but device complexity and data processing requirements increase
Solution Approach 1:
The imaging system divides the acquisition process into multiple discrete projections taken at different perspectives. Each projection captures a specific view of the anatomy, and these segmented views are subsequently reconstructed into a comprehensive three-dimensional model, improving visualization precision while managing system complexity through systematic data collection
Solution Approach 2:
The system transitions from two-dimensional projections to three-dimensional reconstruction by acquiring data from multiple perspectives. This dimensional transformation allows the imaging system to overcome the limitations of single-view imaging and provide comprehensive anatomical visualization with enhanced precision
2Loss of information
If multiple projections are acquired and stitched together to form long views, then image detail and coverage are improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary acquisition of multiple projections with overlapping fields of view before reconstruction. By capturing all necessary data in advance during the imaging phase, the system enables efficient post-processing through stitching and three-dimensional reconstruction, reducing the perceived processing time while maintaining complete image detail
Solution Approach 2:
Multiple projections with overlapping coverage are merged and stitched together to form comprehensive long views. This combining process integrates information from different perspectives into unified images, preserving complete anatomical detail while creating continuous coverage through systematic data fusion
3Measurement precision
If a slotted filter is used to create parallax effect, then three-dimensional information extraction is improved, but image processing complexity increases
Solution Approach 1:
A slotted filter is introduced as an intermediary element between the x-ray source and the subject. This filter creates a parallax effect by allowing x-rays to pass through specific slots at different angles, enabling the system to capture depth information and extract three-dimensional data from the resulting images through analysis of the parallax patterns
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

This approach enables the creation of detailed, three-dimensional models of subjects, facilitating precise surgical interventions and improved anatomical visualization, while also allowing for feature identification and classification within the images.
Implementation Method 1
a moveable source and/or detector that is moveable relative to the subject... The imaging system may include a movable source and/or detector to create a plurality of projections of a subject
Implementation Method 2
The different perspectives may be generated due to a parallax effect between different paths of x-rays from a single source to a detector through the subject. The parallax effect may be formed due to a filter having a plurality of slits or slots through which the x-rays pass
Data Source
AI summary
