Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current X-ray imaging systems require manual adjustment of the X-ray tube to achieve accurate imaging, which is cumbersome and prone to errors, especially when performing multiple images in a day, as the automatic shifting of the tube is not precise enough to maintain image quality without operator intervention.
Innovation Solution
An X-ray imaging apparatus with an X-ray tube shifting mechanism, height-position compensation element, and angle compensation element that automatically adjusts the X-ray tube's position and angle to align with the imaging region, using imaging region data recognition to ensure accurate and deformation-free imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the X-ray tube moves automatically to the position facing the center of the imaging region, then the operation is simplified and productivity is improved, but the imaging precision deteriorates due to insufficient accuracy in positioning the focal point at the target region center
Solution Approach 1:
The control unit receives detection results from the detection element about the subject's anatomical position, automatically adjusts the X-ray tube's height and angle based on this feedback, and achieves precise positioning without manual intervention. This closed-loop feedback mechanism resolves the contradiction by enabling both automatic operation and high precision through real-time positional information.
Solution Approach 2:
The system automatically determines the optimal X-ray tube position based on detected anatomical landmarks and imaging parameters, eliminating the need for operator intervention. The apparatus serves itself by autonomously calculating and adjusting the focal point alignment with the target region center, maintaining both efficiency and precision.
2Manufacturing precision
If manual adjustment of the X-ray tube is performed to achieve accurate focal point alignment, then imaging precision is improved, but the operation complexity increases and productivity decreases
Solution Approach 1:
The manual mechanical adjustment of the X-ray tube is replaced with an automated control system that uses detection elements to identify anatomical landmarks and automatically calculates the required tube position. This substitution eliminates manual operation while maintaining precise focal point alignment, thereby improving both precision and productivity simultaneously.
Solution Approach 2:
The system changes the control parameters of the X-ray tube (height and angle) based on detected anatomical parameters and imaging requirements. By dynamically adjusting these parameters automatically, the system achieves accurate focal point alignment without manual intervention, resolving the contradiction between precision and productivity.
3Adaptability or versatility
If the X-ray tube position is adjusted to match different imaging regions, then adaptability is improved, but the device complexity increases due to additional shifting mechanisms
Solution Approach 1:
The X-ray tube shifting mechanism is designed to perform multiple functions: automatic height adjustment, angle compensation, and focal point alignment for various imaging regions. By integrating these functions into a single multi-functional mechanism controlled by the control unit, the system achieves high adaptability without proportionally increasing overall device complexity.
Solution Approach 2:
The shifting mechanism is designed with dynamic adjustment capabilities, allowing the X-ray tube to automatically adapt its position and angle based on real-time detection of anatomical landmarks and imaging parameters. This dynamic adaptability enables the system to handle various imaging regions efficiently without requiring complex static mechanisms for each possible position.
