Transformable Imaging System Rotor for 360-Degree Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging systems, such as C-Arm systems, have limited flexibility and versatility in acquiring image data, particularly in obtaining 360-degree views, which restricts the generation of clear 3D images.
Innovation Solution
A transformable imaging system with a configurable rotor that can change between a 'C' shaped configuration for limited 360-degree data acquisition and an 'O' shaped configuration for full 360-degree data acquisition, allowing the x-ray source and detector to move relative to the subject in various positions, enabling efficient acquisition of both 2D and 3D image data.
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 ability to acquire 360-degree image data is limited
Solution Approach 1:
The rotor is designed with moveable segments that can dynamically change the configuration from a fixed C-shape to a transformable shape that enables 360-degree rotation. This dynamic reconfiguration allows the system to adapt between different imaging modes (2D fluoroscopy and 3D volumetric imaging) without requiring separate fixed systems, thereby improving versatility while managing complexity through a single transformable structure.
Solution Approach 2:
The C-Arm rotor is divided into multiple moveable segments that can be independently positioned and configured. These segments allow the rotor to transform from a standard C-shape to a configuration that completes the full 360-degree arc, enabling the system to acquire image data from all angles around the patient while maintaining structural integrity.
2Adaptability or versatility
If a single imaging system is used, then the device complexity is reduced, but the versatility to perform both 2D and 3D imaging is limited
Solution Approach 1:
The imaging system is designed with a universal transformable rotor that can perform multiple imaging functions within a single configuration. By enabling the rotor to change shapes between C-Arm and 360-degree configurations, the system provides both 2D fluoroscopy and 3D volumetric imaging capabilities without requiring separate dedicated systems, achieving multi-functionality while controlling overall system complexity.
3Measurement precision
If the rotor is fixed in C-shape, then the system is stable and easy to operate, but image clarity for 3D reconstruction is insufficient
Solution Approach 1:
The rotor transitions from a static C-shape to a dynamic transformable configuration that enables complete 360-degree rotation. This dynamic capability allows the system to capture image data from all angular positions around the patient, providing sufficient data for high-quality 3D reconstruction while maintaining ease of operation through automated transformation sequences.
