Solution Overview
Problem
Existing radiographic imaging systems face challenges in adjusting the orientation of the radiation source and detecting apparatus due to inconsistencies in roll and pitch angles when the apparatus is rotated, leading to potential density differences and diagnostic inaccuracies in radiographs.
Innovation Solution
A radiation detecting apparatus equipped with a hardware processor that detects rotation angles relative to two perpendicular axes and outputs angle information to facilitate precise orientation adjustment, integrated with a radiographic imaging system that includes a radiation emitting apparatus and a console for displaying this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the radiation detecting apparatus is rotated to different orientations, then the imaging flexibility is improved, but the angle adjustment consistency between tube and detecting apparatus deteriorates
Solution Approach 1:
The system dynamically adjusts the tube orientation based on the detected orientation of the radiation detecting apparatus. The changing unit modifies the tube's roll and pitch angles in real-time according to the apparatus's current orientation, ensuring consistent perpendicular alignment between the radiation emission axis and imaging surface regardless of rotation angle.
Solution Approach 2:
The system uses sensors to detect the orientation of the radiation detecting apparatus and provides feedback to the changing unit. This feedback mechanism enables automatic adjustment of the tube orientation to maintain proper alignment, resolving the inconsistency that would otherwise occur during apparatus rotation.
2Device complexity
If manual angle adjustment is used, then the device complexity is reduced, but the angle alignment precision deteriorates
Solution Approach 1:
The system performs self-adjustment by automatically detecting its own orientation and modifying the tube angle accordingly. The changing unit uses the detected apparatus orientation to autonomously calculate and implement the necessary angle corrections, eliminating the need for complex manual adjustment mechanisms while achieving high precision alignment.
3Device complexity
If the tube orientation is fixed relative to the apparatus, then the device complexity is reduced, but the adaptability to different imaging positions deteriorates
Solution Approach 1:
The tube orientation is made dynamic rather than fixed. The changing unit continuously adjusts the tube's roll and pitch angles based on real-time detection of the apparatus orientation, enabling the system to adapt to various imaging positions and angles while maintaining proper perpendicular alignment between the radiation source and imaging surface.
