X-ray Fluoroscope Table Column Displacement for Operator Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray fluoroscope tables in interventional radiology (IVR) lack adequate access from multiple directions, particularly from the head and left/right sides of the object, and suspended-type tables require significant overhead space, which can be impractical in low-ceiling installations.
Innovation Solution
An X-ray fluoroscope table design featuring a stand unit, a support arm unit, a support frame with a top board, an X-ray generator, and an X-ray detector, where the column unit is displaced in the longitudinal direction to allow access from both sides, and the support frame is slidable and rotatable for improved operator positioning and imaging flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a column unit is extended vertically from the support frame with an arm extending orthogonal to the longitudinal direction, then the X-ray generator can be positioned, but access to the object is limited to two directions (head side and one side)
Solution Approach 1:
The column unit is designed to be slidable along the longitudinal direction of the support frame, transforming from a fixed vertical extension to a dynamic structure that can reposition. This allows the X-ray generator to be accessed from multiple directions (head side, right side, and left side) by moving the column unit to different positions along the support frame's longitudinal axis, thereby improving ease of operation without significantly increasing structural complexity
Solution Approach 2:
The column unit's movement along the longitudinal direction of the support frame adds a new degree of freedom to the positioning system. Instead of being constrained to vertical and orthogonal positions only, the column unit can now be positioned at multiple locations along the length of the support frame, enabling access from three directions (head side, right side, left side) and expanding the operational versatility
2Ease of operation
If a suspended-type X-ray fluoroscope table is used to ensure standing position for operators, then access around the top board is improved, but extensive overhead space and installation space are required
Solution Approach 1:
The X-ray generator is extracted from the ceiling suspension system and repositioned to be supported by the column unit attached to the support frame. This removes the dependency on overhead traveling rails and ceiling space, allowing the system to function with minimal overhead clearance while still providing operator access from multiple directions
Solution Approach 2:
The column unit serves as an intermediary structure that bridges the support frame and the X-ray generator. Instead of suspending the generator directly from the ceiling, the column unit acts as a movable support element that can be positioned along the support frame's longitudinal direction, providing the necessary standing positions for operators without requiring extensive overhead space
3Ease of operation
If the end portion on the support frame side of the column unit is displaced in the longitudinal direction, then standing positions on both sides of the support frame are ensured, but the column unit structure becomes more complex
Solution Approach 1:
The column unit is designed with slidable connections that allow it to move along the longitudinal direction of the support frame. This dynamic capability enables the column unit to be positioned at different locations to ensure standing positions on both sides of the support frame, while the slidable mechanism itself remains relatively simple compared to fixed complex structures
Solution Approach 2:
The column unit is divided into separable components with slidable connections to the support frame and the X-ray generator. This segmentation allows each component to be independently positioned and adjusted, simplifying the overall structure while enabling the displacement needed to create standing positions on both sides of the support frame

Function Achieved in This Case
Enables effective access to the object from both sides during IVR procedures, reduces the need for extensive overhead space, and enhances operator workability by ensuring standing positions on both sides of the X-ray generator, facilitating more comprehensive and efficient fluoroscope imaging.
Implementation Method 1
an X-ray generator for irradiating X-rays to the object; and an X-ray detector which is placed opposite from the X-ray generator inside of the support frame, for detecting the X-rays which have permeated the object
