MRI Top Plate Wireless Communication Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional MRI apparatuses face complexity, installation difficulties, and increased costs due to the large number of cables required between the table and the frame, especially when multiple reception RF coils are used simultaneously.
Innovation Solution
The implementation of a movable data transmission/reception and power reception unit within the top plate of the MRI apparatus, which communicates wirelessly with a corresponding unit on the frame, reduces the number of cables needed by enabling wireless transmission of MR data, control signals, and electric power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple reception RF coils are used simultaneously to improve image quality, then image quality is improved, but the number of cables increases causing device complexity and installation difficulty
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The reception RF coil transmits detected signals wirelessly to the frame-mounted wireless communication unit, eliminating the need for physical cable connections between the table and frame. This substitution resolves the contradiction by maintaining multiple reception coils for high image quality while removing the associated cable complexity.
2Measurement precision
If multiple reception RF coils are used simultaneously to improve image quality, then image quality is improved, but installation difficulty increases due to numerous cables
Solution Approach 1:
The wireless communication unit mounted on the frame receives signals wirelessly from the reception RF coil, replacing the complex cable installation process. This eliminates the need to route and connect multiple cables between the table and frame, significantly simplifying the installation process while maintaining the capability to use multiple reception coils for high-quality imaging.
3Adaptability or versatility
If a large connector is used to connect multiple cables between table and frame to support multiple RF coils, then connectivity is improved, but the weight of the movable table increases
Solution Approach 1:
The patent replaces the large physical connector on the table with a wireless transmission unit. The reception RF coil transmits signals wirelessly to the frame-mounted communication unit, eliminating the need for heavy connectors and cable assemblies on the movable table. This maintains full connectivity for multiple RF coils while significantly reducing the weight of the movable table component.
4Adaptability or versatility
If multiple connectors are disposed on the top plate to support multiple reception RF coils, then adaptability is improved, but device complexity and cost increase
Solution Approach 1:
The wireless communication unit mounted on the frame serves as a universal interface for all reception RF coils. Instead of requiring separate connectors for each coil on the table, the wireless system provides a single communication channel that can handle signals from multiple coils, thereby maintaining adaptability while reducing overall system complexity and cost.

AI summary
A magnetic resonance imaging apparatus includes a top plate on which a reception coil for receiving a magnetic resonance signal is disposed, a top plate communication unit, and a frame communication unit. The top plate communication unit is disposed in an interior of the top plate and configured to be movable inside the top plate. The frame communication unit is disposed in a position at one end of a frame having a bore where the top plate is inserted. The magnetic resonance imaging apparatus executes communication between the top plate communication unit and the frame communication unit.
