Mobile Robotic X-ray Machines for Biplane Imaging Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multiplane medical imaging systems, particularly biplane X-ray systems, are cumbersome and limit access to patients due to their fixed positions, restricting movement and image quality during angiographic examinations, as they require radiography only for a limited time and do not allow sufficient mobility or complex angulations for three-dimensional reconstructions.
Innovation Solution
A multiplane medical imaging system with two X-ray machines mounted on mobile robotic devices, allowing each machine to move independently on the floor and ceiling, respectively, with a central processing unit controlling their positions and movements to optimize access and image capture, enabling increased degrees of freedom and flexibility during examinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If X-ray machines are fixed to the floor or ceiling, then image quality and stability are improved, but access to the patient and mobility are worsened
Solution Approach 1:
The patent applies the dynamics principle by transitioning from fixed X-ray machines to mobile robotic devices that can dynamically position themselves. The robotic devices include mobile platforms with wheels or tracks that allow movement to and from the patient area, enabling both high-quality imaging when needed and easy access when the imaging function is not required.
2Ease of operation
If X-ray machines are made mobile, then access to the patient is improved, but image quality and stability are worsened
Solution Approach 1:
The patent applies preliminary action by having the mobile robotic devices position themselves in predetermined optimal locations before imaging begins. The system pre-positions the X-ray machines at specific coordinates and orientations that have been calculated to provide the best imaging angles, ensuring that when imaging commences, the equipment is already in the correct position for high-quality image acquisition.
3Adaptability or versatility
If multiple X-ray machines are used for multiplane imaging, then imaging capability is improved, but device complexity and space requirements are worsened
Solution Approach 1:
The patent applies universality by designing mobile robotic devices that can perform multiple functions. Each robotic device not only positions and stabilizes an X-ray machine but also provides navigation, collision avoidance, and positioning assistance for the examination table. This multi-functionality reduces the need for separate specialized equipment for each function, thereby managing complexity while enhancing multiplane imaging capabilities.
4Measurement precision
If X-ray machines are positioned close to the examination table, then imaging precision is improved, but collision risks and access limitations are worsened
Solution Approach 1:
The patent applies feedback through navigation systems that continuously monitor the positions of mobile X-ray machines and the examination table. Sensors detect relative positions and distances, providing real-time feedback to the control system. This enables dynamic adjustment of machine positions to maintain optimal imaging angles while preventing collisions by alerting operators or automatically adjusting positions when potential conflicts are detected.
