Problem
Current medical imaging systems are inefficient and inaccurate in locating target subjects during surgical operations, often requiring additional devices that occupy space and complicate the navigation process, especially when adjusting X-ray radiation directions to center lesions from different perspectives.
Innovation Solution
An X-ray system incorporating an X-ray source, detection component, and positioning components, including laser beams that intersect to determine a target point, allowing for precise localization of a region of interest without the need for additional navigation devices, by using a C-arm or G-arm configuration and positioning markers to align anatomical images and patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional navigation devices are used to locate the target subject in real-time, then the accuracy of target localization is improved, but the device complexity and space occupation in the operation room increase
Solution Approach 1:
The patent integrates the navigation function directly into the existing X-ray imaging system by mounting laser components on the C-arm structure. This merging eliminates the need for separate navigation devices and reduces overall system complexity while maintaining real-time localization accuracy through the combined imaging and positioning capabilities.
Solution Approach 2:
The X-ray system is enhanced with multi-functionality by incorporating laser positioning components that enable both imaging and navigation functions within a single system. This universal approach allows the system to perform multiple tasks (imaging, positioning, and navigation) without requiring additional specialized devices.
2Measurement precision
If additional navigation devices are used for real-time surgical navigation, then the navigation accuracy is improved, but the space occupation in the operation room increases
Solution Approach 1:
By integrating the navigation system into the existing C-arm structure, the patent eliminates the need for separate navigation equipment that would occupy additional space. The laser components are mounted on the C-arm, utilizing its structural space efficiently and reducing the overall footprint in the operation room.
3Measurement precision
If the operator adjusts X-ray radiation direction to center lesions from different perspectives, then the imaging accuracy is improved, but the operation time and efficiency decrease
Solution Approach 1:
The laser positioning system performs preliminary action by pre-identifying and marking the target location on the patient's body before X-ray imaging. This preliminary positioning guides the operator to the correct anatomical location, reducing the need for repeated adjustments and multiple imaging attempts, thereby saving time while maintaining imaging accuracy.
Solution Approach 2:
The system provides real-time feedback through laser positioning markers that indicate the precise target location. This feedback mechanism allows the operator to quickly verify correct positioning without extensive trial and error adjustments, reducing operation time while ensuring accurate imaging from the appropriate perspectives.
4Measurement precision
If multiple X-ray beams are emitted from different directions to locate the target point, then the localization accuracy is improved, but the radiation exposure increases
Solution Approach 1:
The laser positioning system performs preliminary action by marking the target location before X-ray exposure. This allows the operator to plan and execute imaging from optimized angles with minimal necessary radiation, as the target is already identified and marked by the laser system, reducing the need for multiple exploratory X-ray beams.
