X-Ray Imaging With Switchable Subject Support for Flexible Examinee Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray imaging devices face challenges in acquiring images when the examinee's position changes relative to the device, complicating entry and movement due to limited space and device structure, necessitating a solution that allows imaging from different positions without moving the imaging parts.
Innovation Solution
An X-ray imaging apparatus with a subject support part that can switch and attach/detach to different connection states, aligning the subject to the imaging position from either side, allowing the apparatus to acquire images without relocating the X-ray generator and detector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the subject support part is fixed in a single position, then the imaging part structure is simple, but the examinee cannot be positioned from different directions
Solution Approach 1:
The subject support part is designed to be dynamically reconfigurable, allowing it to switch between different connection states. The support part can be attached to either the first side or the second side of the column, enabling the examinee to be positioned from different directions while maintaining a relatively simple imaging part structure.
Solution Approach 2:
The subject support part is segmented into detachable components that can be connected to different sides of the column. This segmentation allows the support part to be reconfigured for different examinee positions without requiring the entire imaging apparatus to be moved or reconfigured.
2Adaptability or versatility
If the imaging part is moved to accommodate different examinee positions, then all positions can be imaged, but the imaging part structure becomes complex and requires movement mechanisms
Solution Approach 1:
Instead of moving the imaging part to accommodate different examinee positions, the invention inverts the approach by moving the subject support part to different sides of the column. This allows the examinee to be repositioned relative to the fixed imaging part, achieving the same adaptability without the complexity of moving the imaging part.
3Area of stationary object
If the shielded room space is limited, then the device fits in small spaces, but the examinee entry and movement path becomes complicated
Solution Approach 1:
The subject support part's dynamic reconfigurability allows the examinee entry path to be adapted based on available space. By attaching the support part to different sides of the column, the examinee can enter from different directions, simplifying the movement path according to the specific layout and space constraints of the shielded room.
