Rotating X-Ray Stand Column for Safe 3D Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray imaging systems face limitations in three-dimensional imaging due to the stationary position of the stand column assembly, which restricts the rotation of the X-ray detector relative to the subject, leading to safety concerns and poor imaging effects when subjects are rotated for adjustment.
Innovation Solution
A stand column assembly with a rotatable base and a rotatable X-ray detector, equipped with a stand column rotation mechanism and translation mechanism, allowing the X-ray detector to adjust its position and orientation relative to the subject, enabling three-dimensional imaging without subject rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stand column assembly is made stationary to ensure stability, then the safety and stability of the system is improved, but the rotation range of the X-ray detector relative to the subject is limited, worsening the three-dimensional imaging capability
Solution Approach 1:
Instead of rotating the subject to achieve different imaging angles, the patent inverts the approach by making the stand column assembly rotatable while keeping the subject stationary. The base is configured to rotate around the subject, allowing the X-ray detector to capture images from multiple angles without moving the patient, thereby solving both safety concerns and imaging capability limitations.
2Adaptability or versatility
If the subject is rotated to expand the rotation range of the X-ray detector, then the three-dimensional imaging capability is improved, but safety problems such as subjects falling and poor imaging effects due to shaking occur
Solution Approach 1:
The patent applies inversion by reversing which component rotates - instead of rotating the subject, the stand column assembly with the X-ray detector rotates around the stationary subject. This eliminates safety hazards associated with subject rotation while maintaining the ability to achieve three-dimensional imaging through multiple angle captures.
3Device complexity
If the stand column assembly is made stationary to simplify the structure, then the device complexity is reduced, but the position adjustment range of the X-ray detector is limited, worsening the imaging flexibility
Solution Approach 1:
The patent transitions from a static stand column assembly to a dynamic one by adding a rotation mechanism to the base. The base can rotate around the subject within a predetermined range, enabling the X-ray detector to adjust its position and orientation. This dynamic capability enhances imaging flexibility while maintaining reasonable structural complexity through modular design.

AI summary
Provided in the present application are a stand column assembly for an X-ray imaging system and an X-ray imaging system. The stand column assembly includes a base and a stand column that are assembled together. The base is configured to be disposed on a horizontal supporting surface and stationary relative to the supporting surface, and is configured to support a subject to be imaged. The stand column includes a main body portion and an X-ray detector, the main body portion being rotatably connected to the base and being erected opposite the supporting surface, and the X-ray detector being mounted on the main body portion. Further, there exists an axis of rotation perpendicular to the supporting surface and passing through the base, and the main body portion is rotatable about the axis of rotation relative to the base within a predetermined range.
