Flat Panel Detector Retreating Mechanism for Proximity X-ray Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional proximity operation fluoroscopic imaging apparatuses face difficulties in retreating heavy image intensifiers and cameras, requiring large and strong deck units and floaters, which complicates operation, especially for operators of shorter stature, and limits the height of the tower unit.
Innovation Solution
The apparatus incorporates a lightweight flat panel detector supported by a deck unit and floater, with a rotation mechanism allowing the detector to move in a direction crossing the floater's path, enabling operation at arbitrarily positioned heights and reducing the size of the sliding area, thus improving operability and allowing a higher tower unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy image intensifiers and cameras are used, then X-ray fluoroscopy imaging quality is maintained, but the deck unit and floater must be large and strong, complicating operation and limiting tower unit height
Solution Approach 1:
The patent changes the weight parameter of the X-ray detection element from heavy (image intensifier) to lightweight (flat panel detector), which fundamentally alters the structural requirements of the supporting deck unit and floater, enabling easier operation while maintaining imaging quality
Solution Approach 2:
The patent replaces the mechanical support system designed for heavy image intensifiers with a optimized mechanical system for lightweight flat panel detectors, allowing reduction of deck unit and floater size while improving operability
2Reliability
If heavy image intensifiers and cameras are used, then imaging function is ensured, but the deck unit and floater must be large and strong, increasing device complexity
Solution Approach 1:
By changing the weight parameter of the detection element to lightweight, the structural complexity of the deck unit and floater is reduced, as smaller and simpler components can support the lighter load while maintaining imaging function
3Ease of operation
If the tower unit height is limited, then operability for short operators is improved, but the deck unit cannot be positioned at optimally high locations
Solution Approach 1:
The lightweight flat panel detector enables the tower unit to achieve greater height while maintaining operability, as the reduced weight allows for taller structural support without compromising the ease of moving and positioning the detection element
4Ease of operation
If the deck unit is made smaller to improve operability, then the sliding area is reduced, but the support structure for heavy detectors cannot be maintained
Solution Approach 1:
By changing the weight parameter of the detection element to lightweight, the support structure can be reduced in size and strength while still adequately supporting the detector, enabling smaller deck unit with improved maneuverability

AI summary
A proximity operation fluoroscopic imaging apparatus allows a retreating operation for a X-ray detection element at an arbitrarily-positioned height. The X-ray imaging is carried out using the proximity operation fluoroscopic imaging apparatus a hanging-type X-ray irradiation element, a deck unit 26, supporting a flat panel detector 13, moves to a retreating position. The deck unit 26, supports a flat panel detector 13, and enables a retreating operation in the area of a subject M side of a tower unit 25, so that such a retreating operation is feasible regardless a height-position of the deck unit 26 supports the flat panel detector 13.
