Multi-Part Magnetic Resonance Local Coil With Low-Height Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transporting patients, especially unwell or heavy individuals, from one support surface to another in magnetic resonance apparatuses is cumbersome due to the height of conventional local coil arrangements, requiring significant effort from radiology staff.
Innovation Solution
A magnetic resonance local coil arrangement with a bottom section having a height of less than ⅓ of the total height, allowing easier patient positioning by reducing the barrier during lateral transport, and featuring a top section that connects seamlessly with the bottom section to form a spatial volume for patient support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bottom section has a reduced height of less than 1/3 of the total height, then the ease of patient transfer is improved, but the volume of the coil arrangement is reduced
Solution Approach 1:
The coil arrangement is divided into a bottom section and a top section, with the bottom section having a reduced height of less than 1/3 of the total height. This segmentation allows the coil to maintain its functional volume in the top section while reducing the barrier height that obstructs patient transfer, thereby resolving the contradiction between ease of operation and volume preservation.
2Ease of operation
If the bottom section has a reduced height, then the effort required for patient positioning is reduced, but the spatial volume available for patient support is reduced
Solution Approach 1:
The coil arrangement extends primarily in the longitudinal direction rather than uniformly in all dimensions. The bottom section is reduced in height (vertical dimension) while the top section maintains adequate volume for patient support through extended length (longitudinal dimension), thus reducing positioning effort while preserving necessary support volume.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easier and safer patient transfer by minimizing the height obstruction, simplifying the workflow, and reducing the effort required for positioning patients on the patient support apparatus.
Implementation Method 1
The excited atomic nuclei emit magnetic resonance signals that are received by one or more magnetic resonance local coil arrangements
Implementation Method 2
The patient is subjected to high frequency electromagnetic signals (RF signals) in order to excite the atomic nuclei of the patient

AI summary
A magnetic resonance local coil arrangement, a system with a magnetic resonance local coil arrangement and patient support apparatus, a magnetic resonance apparatus, and a use of such apparatuses are provided. The magnetic resonance local coil arrangement includes a bottom section and a top section. In a connected state, the bottom section and the top section delimit a spatial volume in which a body part of a patient may be supported during a magnetic resonance examination. The bottom section is configured to be positioned on a patient support apparatus of a magnetic resonance apparatus for performing the magnetic resonance examination. The bottom section and the top section have a total height in a connected state. The bottom section has a height of less than ⅓ of the total height.
