Solution Overview
Problem
Conventional C-arm X-ray systems are limited by their inability to generate multiple X-ray characteristics, necessitating separate systems for different applications like interventional radiography and angiography, which require distinct anode plate angles.
Innovation Solution
An X-ray emitter assembly with a control unit and mechanical adjustment unit allows automatic adjustment of the X-ray emitter orientation based on selected examination information, enabling the same system to produce varying X-ray characteristics suitable for multiple applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different C-arm X-ray systems are used for different applications (angiography, interventional radiography), then each application receives optimized X-ray characteristics, but the device complexity and cost increase due to requiring multiple specialized systems
Solution Approach 1:
The patent implements a single C-arm X-ray system capable of performing multiple applications (angiography, interventional radiography, neuroradiology) by dynamically adjusting the anode plate angle. The X-ray emitter is designed with an adjustable anode plate that can be tilted to different angles, allowing one system to replace multiple specialized systems while maintaining optimized X-ray characteristics for each application
Solution Approach 2:
The anode plate is made dynamically adjustable during operation. The patent describes a mechanical adjustment mechanism that allows the anode plate angle to be changed between different predetermined angles corresponding to different applications. This dynamic adjustability enables the system to adapt its X-ray characteristics on-demand rather than being fixed for a single application
2Reliability
If the anode plate angle is fixed for a specific application, then the X-ray characteristics are optimized for that application, but the system cannot be used for other applications requiring different X-ray characteristics
Solution Approach 1:
The anode plate is designed with dynamic angle adjustment capability, allowing it to be tilted to different predetermined angles corresponding to different applications. The mechanical adjustment mechanism maintains stable positioning at each angle while enabling transitions between angles, thus preserving X-ray characteristic consistency for each application while expanding the overall application range
Solution Approach 2:
The patent changes the physical parameter of the anode plate angle to generate different X-ray characteristics. By adjusting the anode plate to different angles, the system modifies the X-ray beam parameters (dose, cross-section) to match requirements for different applications, thereby achieving both reliability for each application and versatility across applications
3Productivity
If multiple specialized C-arm X-ray systems are deployed for different applications, then each system provides optimized performance, but the cost and space requirements increase
Solution Approach 1:
The patent creates a universal C-arm X-ray system that can perform multiple specialized applications through anode plate angle adjustment. This single multi-functional system replaces what would otherwise require multiple separate specialized systems, reducing the quantity of equipment needed while maintaining application-specific performance optimization
Solution Approach 2:
The patent combines multiple application capabilities into a single X-ray system by integrating the adjustable anode plate mechanism. Functions that would require separate systems (angiography unit, interventional radiography unit, neuroradiology unit) are merged into one system that can be configured for each application through angle adjustment
