Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing C-arm X-ray machines require complex driving mechanisms and long shooting times for obtaining multiple projection images due to the fixed position of the X-ray generator, making precise control difficult and increasing the machine's footprint.
Innovation Solution
An X-ray imaging apparatus with a C-shaped arm that allows the X-ray generator to rotate and move separately from the detector via a guide rail and drive part, enabling independent movement and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire C-shaped arm is rotated to obtain multiple projection images, then the imaging angle range is achieved, but the device complexity and driving mechanism complexity increase
Solution Approach 1:
The system divides the rotation function into two independent parts: the C-shaped arm remains stationary while the X-ray generator rotates independently on its own axis. This segmentation eliminates the need for complex mechanisms to rotate the entire arm, achieving multiple projection angles through the generator's independent rotation capability.
2Adaptability or versatility
If the entire C-shaped arm is rotated to obtain multiple projection images, then the imaging angle range is achieved, but the shooting time increases
Solution Approach 1:
By separating the rotation function from the C-shaped arm and assigning it to the X-ray generator alone, the system enables faster repositioning. The generator can rotate independently to different angles without moving the entire arm structure, significantly reducing the time required to acquire multiple projection images.
3Adaptability or versatility
If the entire C-shaped arm is rotated to obtain multiple projection images, then the imaging angle range is achieved, but the control precision decreases
Solution Approach 1:
The independent rotation of the X-ray generator allows for precise angular control using dedicated drive mechanisms positioned at the generator level. This segmentation enables fine-adjustment capabilities and more accurate positioning compared to rotating the entire C-shaped arm, improving control precision for acquiring projection images at specific angles.
4Adaptability or versatility
If a complex driving mechanism is used to rotate the C-shaped arm, then the imaging angle range is achieved, but the load and footprint increase
Solution Approach 1:
The system segments the rotation function to the X-ray generator only, eliminating the need for heavy-duty drive mechanisms on the C-shaped arm. The generator's compact rotation system requires less mechanical infrastructure, reducing both the load on the arm structure and the overall footprint of the imaging system while maintaining the ability to achieve multiple projection angles.
