Movable MRI Magnet and X-Ray Imaging Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current combined MRI and X-Ray imaging systems often require patients to be transferred between different imaging modalities, limiting access and efficiency during medical procedures, especially in intra-operative settings where the presence of multiple machines restricts access to the patient.
Innovation Solution
A patient support table system that allows for a patient to remain stationary while switching between MRI and X-Ray imaging, with a movable MRI magnet that can be positioned over the patient for MRI imaging and then moved out of the way for X-Ray imaging, enabling simultaneous or sequential imaging without patient transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple imaging machines (MRI and X-Ray) are present simultaneously, then comprehensive diagnostic capability is improved, but access to the patient is restricted
Solution Approach 1:
The imaging system is segmented into separate MRI and X-Ray components that can be independently positioned and operated. The MRI scanner and X-Ray scanner are distinct modules that can be moved to different locations around the operating table, allowing the surgical team to access the patient from all sides while both imaging modalities remain available.
Solution Approach 2:
The system transitions from a single-location imaging approach to a multi-dimensional arrangement where MRI and X-Ray scanners can be positioned at different spatial locations around the patient. This spatial distribution in multiple dimensions allows simultaneous access to the patient by surgical personnel while maintaining comprehensive imaging capability.
2Adaptability or versatility
If patient is transferred between imaging systems, then both MRI and X-Ray imaging can be performed, but time is lost and efficiency is reduced
Solution Approach 1:
The MRI and X-Ray imaging systems are merged into a single integrated platform centered around a common operating table. Both imaging modalities can image the patient simultaneously or sequentially without requiring patient transfer, as the patient remains positioned on the same table throughout the procedure.
Solution Approach 2:
The operating table serves as a universal platform that supports both MRI and X-Ray imaging operations. The table is designed with features that are compatible with both imaging modalities, eliminating the need for separate transfer mechanisms and enabling seamless switching between imaging types.
3Reliability
If magnet is stationary for MRI imaging, then MRI quality is maintained, but flexibility for intra-operative imaging is reduced
Solution Approach 1:
The MRI magnet is designed with dynamic positioning capabilities, allowing it to be moved to different locations around the operating table as needed. The magnet can be repositioned to image different anatomical regions or to accommodate different surgical approaches, while maintaining the magnetic field stability required for high-quality imaging when positioned.
Solution Approach 2:
A movable positioning mechanism serves as an intermediary between the stationary MRI magnet and the dynamic surgical environment. This intermediary system allows the magnet to be smoothly repositioned to different locations while maintaining field stability during imaging, bridging the gap between the need for motion and the need for stable imaging.

AI summary
A patient table for a common imaging system including Magnetic Resonance and X-Ray retains the patient stationary in position prior to, during and subsequent to the imaging and includes a base, a patient support portion cantilevered from the base and a mattress. A safety system is provided for controlling the operation of the magnet and MR system and the X-Ray systems to allow effective safe operation and controls the movement of the magnet to the table and the movement of the X-Ray imaging systems to and from the table to locations where they do not interfere with the MR imaging.
