Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional C-Arm imaging systems have limited flexibility and versatility, as they are fixed in geometry, restricting the acquisition of comprehensive image data and hindering the generation of clear 3D images.
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 both 2D and 3D image data by changing from a 'C' shaped configuration to an 'O' shaped configuration, allowing for 360-degree data acquisition around the subject.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed C-Arm geometry is used, then the system structure is simple and stable, but the versatility and ability to acquire comprehensive image data is limited
Solution Approach 1:
The C-Arm imaging system employs a transformable rotor that can dynamically change its geometric configuration between a C-shaped arrangement (with the detector and source separated by an arc) and an O-shaped arrangement (where the detector and source are positioned to form a complete circle around the subject). This dynamic reconfiguration capability allows the same physical system to adapt to different imaging requirements, enabling both 2D fluoroscopic imaging and 3D volumetric imaging without requiring multiple separate systems.
2Measurement precision
If a fixed C-Arm geometry is used, then the system is easy to operate, but the ability to generate clear 3D images is hindered
Solution Approach 1:
The system transforms from a static C-Arm to a dynamic transformable rotor that can reconfigure between C-shaped and O-shaped geometries. When 3D imaging is required, the rotor transforms to the O-shaped configuration, allowing the detector and source to be positioned optimally for 360-degree data acquisition around the subject, thereby enabling clear 3D image generation while maintaining ease of operation through automated transformation sequences.
3Adaptability or versatility
If multiple imaging systems are used for 2D and 3D imaging, then comprehensive image data can be acquired, but the device complexity and cost increase
Solution Approach 1:
The transformable rotor is designed to perform multiple imaging functions within a single system. By reconfiguring between C-shaped and O-shaped arrangements, the same physical apparatus can execute both 2D fluoroscopic imaging protocols and 3D volumetric imaging protocols, eliminating the need for separate dedicated 2D and 3D imaging systems and thereby reducing overall system complexity and cost.
Solution Approach 2:
The invention merges the functionality of separate 2D and 3D imaging systems into a single unified transformable rotor system. The C-shaped configuration handles 2D imaging requirements while the O-shaped configuration handles 3D imaging requirements, with the transformation mechanism serving to combine these previously separate functions into one integrated system that can adapt its geometry based on the imaging task at hand.
