Magnetic Resonance Coil Recess Guiding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current magnetic resonance facilities require complex and time-consuming cabling for local coils, which can disrupt scans and complicate signal transmission, and often necessitate different coil setups for various scan geometries, limiting flexibility.
Innovation Solution
A magnetic resonance facility design where a coil facility is guided displaceably within recesses on the object table, allowing for flexible positioning and automatic electrical or optical connections, reducing the need for additional cabling and enhancing signal transmission and power supply management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If local coils are arranged directly on the object to be examined, then signal reception quality is improved, but arrangement time increases and cabling complexity increases
Solution Approach 1:
The coil facility is divided into separate modules (local coils) that can be independently positioned and connected to the object table at multiple locations, allowing flexible arrangement without complex integrated cabling
Solution Approach 2:
The connecting portion is guided displaceably along the longitudinal direction of the recess, adding a degree of freedom in positioning the coil facility along the length of the object table, enabling flexible geometric adaptation
2Ease of operation
If rigid coil supports with predefined positions are used, then arrangement complexity is reduced, but flexibility for different scan geometries is lost
Solution Approach 1:
The coil facility transitions from fixed predefined positions to a dynamic system where the connecting portion can be displaced along the recess to various positions, allowing adaptation to different scan geometries while maintaining ease of connection
Solution Approach 2:
The object table with its recesses and connecting devices serves multiple functions: mechanical support, electrical connection, and positioning guidance, while the coil facility can be used for various scan geometries (head, back, ankle coils) with the same basic structure
3Reliability
If complex cabling is used for coil connections, then electrical connections are established, but scan artifacts increase and accessibility is reduced
Solution Approach 1:
The connecting portion and its guiding mechanism are extracted from the object table surface, allowing cables to be routed through dedicated pathways (recesses) rather than across the scanning region, reducing interference with the magnetic resonance scan
Solution Approach 2:
The recess acts as an intermediary structure that guides the connecting portion and cables from the coil facility to the object table's electrical connection points, organizing cable routing away from the scanning region and reducing scan artifacts

AI summary
A magnetic resonance facility is provided. The magnetic resonance facility includes at least one object table configured to mount an object to be examined and at least one coil facility embodied separately from the object table, which includes at least one local coil and at least one connecting portion, which may be introduced into at least one recess of the object table and may be held there to hold the coil facility. The connecting portion in the recess is guided displaceably along a longitudinal direction of the recess between different positions in which it may be held. At least one coil-facility-side connecting device is arranged on the connecting portion and may establish an electrical connection for the power supply and/or for signal transmission between the coil facility and the object table and/or at least one optical connection for signal transmission between the coil facility and the object table.
