C-Arm X-Ray Transmitter and Receiver Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray arrangements for medical workstations, particularly C-arm-shaped frames, lack flexibility in adjusting the relative pose of X-ray transmitters and receivers, limiting their operational range and accessibility in confined medical environments.
Innovation Solution
The implementation of an adjustment device with multiple degrees of freedom, including joints and linear guides, allows independent adjustment of the X-ray transmitter and receiver relative to the C-arm-shaped frame, enabling changes in position, orientation, and distance, as well as tilting and inclining, to expand the operational range without requiring significant translational displacement of the entire device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire C-arm-shaped frame is translated to change the operational range, then the imaging coverage can be expanded, but the device complexity and space requirements increase significantly
Solution Approach 1:
The patent divides the X-ray system into separable components: the C-shaped frame remains stationary while the X-ray transmitter and receiver are mounted on independently adjustable supports. This segmentation allows each component to be optimized separately and enables flexible positioning without moving the entire device, resolving the contradiction between operational range and device complexity.
Solution Approach 2:
The patent introduces dynamic adjustment capabilities through movable supports with degrees of freedom. The transmitter support and receiver support can be independently positioned along guide rails and rotated, allowing the system to adapt to different imaging scenarios without translating the entire C-arm frame, thus expanding operational range while maintaining structural simplicity.
2Adaptability or versatility
If the X-ray transmitter and receiver are fixed on the C-arm frame, then the structural stability is maintained, but the flexibility and accessibility in confined medical environments are limited
Solution Approach 1:
The patent implements dynamic positioning systems where the transmitter and receiver can be adjusted along guide rails and rotated about axes. This allows the system to adapt to various imaging angles and patient positions while the C-arm frame itself remains stationary and structurally stable, resolving the contradiction between flexibility and structural stability.
Solution Approach 2:
The patent introduces intermediary components (movable supports, guide rails, and rotation joints) between the fixed C-arm frame and the X-ray components. These intermediaries enable flexible positioning of the transmitter and receiver while the frame remains stable, allowing the system to access confined medical environments without compromising structural integrity.
3Adaptability or versatility
If multiple adjustment mechanisms are added to increase degrees of freedom, then the operational flexibility is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent segments the adjustment functionality into modular components: linear guides for translational movement and rotation joints for angular adjustment. Each module performs a specific function and can be manufactured independently using standard mechanical components, reducing overall manufacturing complexity while providing comprehensive adjustment capabilities.
Solution Approach 2:
The patent designs the adjustment mechanisms to serve multiple functions: the movable supports enable both translational movement along guide rails and rotational adjustment about axes. This multi-functionality reduces the number of separate components needed, simplifying manufacturing while maximizing operational flexibility for various imaging configurations.

AI summary
An X-ray arrangement for a medical work station includes a frame having a first frame section supporting an X-ray transmitter and a second frame section opposite the first frame section and supporting an X-ray receiver. The medical work station further includes an adjustment device configured to change a relative pose of at least one of the X-ray transmitter or the X-ray receiver relative to the frame by adjusting at least one of the pose of the X-ray transmitter at the first frame section or the pose of the X-ray receiver (at the second frame section independently of one other. In one aspect, the frame may be shaped as a C-arm.
