X-Ray Imaging Support Switching 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 allocation in shielded rooms.
Innovation Solution
An X-ray imaging apparatus with a subject support part that can switch and attach/detach to different connection states, allowing alignment of the subject to the imaging position from either side without moving the imaging part, comprising a column, support arm, rotary arm, and X-ray generator/detector configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the subject support part is fixed in a single position, then the imaging structure is simple and stable, but the examinee cannot enter from different directions and the shielded room requires more space
Solution Approach 1:
The subject support part is designed to be switchable between different connection states (first and second connection states), allowing it to dynamically change its position and orientation. This enables the examinee to approach from different directions while maintaining a relatively simple overall structure compared to completely movable imaging components.
Solution Approach 2:
The subject support part is separated into a detachable component that can be switched between different connection states on the column, independent from the fixed imaging part. This segmentation allows the support structure to adapt while the imaging system remains simple and stable.
2Ease of operation
If the imaging part is moved to accommodate different examinee positions, then examinee access is improved, but the imaging system complexity and potential misalignment increase
Solution Approach 1:
Instead of moving the imaging part to accommodate different examinee positions, the invention inverts the approach by making the subject support part switchable while keeping the imaging part fixed. This ensures imaging alignment is maintained while still allowing flexibility in examinee positioning.
Solution Approach 2:
The system is segmented into a movable subject support part and a fixed imaging part. The subject support part can be switched between different connection states to accommodate various examinee positions, while the imaging part remains stationary to maintain precise alignment and manufacturing precision.
3Area of stationary object
If the shielded room is designed with limited space, then the room size is reduced, but the examinee movement path becomes complicated
Solution Approach 1:
The switchable subject support part allows the examinee to approach from different directions depending on which connection state is active, simplifying the movement path within the limited space of the shielded room. The system adapts to different entry scenarios without requiring a larger room.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables X-ray imaging from different examinee positions without relocating the imaging components, ensuring sufficient space for entry into shielded rooms and maintaining consistent imaging quality.
Implementation Method 1
an X-ray generator and an X-ray detector provided at opposite ends of the rotary arm and facing each other
Implementation Method 2
X-ray imaging is a radiographic method that utilizes the penetration ability and straightness of X-rays. In X-ray imaging, the difference in X-ray transmittance depending on the internal structures of an object is displayed as a gray level X-ray image based on the X-ray attenuation accumulated during the process of penetrating the object
