Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional C-Arm imaging systems have limited flexibility and versatility in acquiring image data, as they are typically fixed in a single configuration, restricting the range of image acquisition and the quality of three-dimensional image reconstruction.
Innovation Solution
A transformable imaging system with a configurable housing and rotor that allows the x-ray source and detector to move in two configurations, enabling efficient acquisition of two-dimensional and three-dimensional image data by changing from a 'C' shaped configuration to an 'O' shaped configuration, allowing for 360-degree image acquisition around the subject.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed C-Arm configuration is used, then the system structure is simple and stable, but the flexibility and versatility in acquiring image data is limited
Solution Approach 1:
The C-Arm imaging system employs a transformable arm that can dynamically change its geometric configuration between a C-shaped arrangement (with the detector and source separated) and an O-shaped arrangement (with the detector and source adjacent). This dynamic reconfigurability allows the system to adapt between different imaging modes (fluoroscopy and 3D tomography) without requiring multiple separate systems, thereby resolving the contradiction between versatility and complexity.
2Measurement precision
If a fixed C-Arm configuration is used, then the device structure is simple, but the quality of three-dimensional image reconstruction is restricted
Solution Approach 1:
The imaging system is designed with universal multi-functionality, where a single C-Arm system can perform both traditional fluoroscopy imaging and 3D tomography imaging by transforming its arm configuration. The transformable design enables the system to acquire image data from multiple angles and positions, providing the comprehensive data set necessary for high-quality 3D reconstruction while maintaining a single unified platform.
3Adaptability or versatility
If multiple imaging systems are used to achieve versatile image acquisition, then the adaptability is improved, but the device complexity and cost increase
Solution Approach 1:
The invention merges the functionality of multiple separate imaging systems (fluoroscopy system and 3D tomography system) into a single integrated C-Arm platform. By combining these functions and enabling the arm to transform between configurations, the system achieves the versatility of multiple systems while reducing overall complexity and eliminating the need for separate equipment in the operating room.
