Real-Time Acoustic Feedback for MRT Coil Tuning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional tuning process of magnetic resonance tomograph (MRT) coil arrangements is tedious, time-consuming, and lacks real-time feedback, requiring service personnel to rely on trial-and-error methods and mental calculations, while working under stress and close to high-voltage electrical components.
Innovation Solution
A method and device providing real-time acoustic and/or mechanical feedback to assist in tuning adjustment parameters, such as resonant frequencies and decoupling factors, by detecting actual and required values and outputting signals to operators, facilitating quicker and more precise tuning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional trial-and-error tuning method is used, then service personnel can adjust parameters, but tuning time is excessive and quality is low
Solution Approach 1:
The patent implements real-time acoustic feedback that continuously monitors adjustment parameters and provides immediate auditory signals to the service personnel. This feedback mechanism eliminates the trial-and-error approach by directly indicating when parameters are within tolerance ranges, dramatically reducing tuning time and improving productivity.
Solution Approach 2:
The patent replaces the mechanical/visual monitoring process with an acoustic signaling system. Instead of service personnel visually checking displays and mentally calculating deviations, the system converts parameter status into audible signals that can be perceived without diverting visual attention from the tuning process.
2Loss of information
If service personnel monitor display readings, then parameter values can be read, but visual attention is diverted from the tuning process
Solution Approach 1:
The patent substitutes visual display monitoring with acoustic signaling. The system converts parameter deviation information into audible signals that reach the service personnel without requiring them to look away from the coil arrangement, maintaining operational continuity while preserving information transfer.
Solution Approach 2:
The acoustic signal acts as an intermediary that bridges the gap between the parameter monitoring system and the service personnel. Instead of direct visual contact with displays, the intermediary acoustic channel conveys parameter status information while allowing uninterrupted visual attention to the tuning task.
3Manufacturing precision
If real-time feedback is provided, then tuning quality improves, but device complexity increases
Solution Approach 1:
The patent implements a feedback system that compares actual adjustment parameters with required values and provides real-time acoustic indication when tolerances are met. This feedback mechanism enhances tuning precision by eliminating guesswork and trial-and-error, guiding service personnel directly to optimal settings.
Solution Approach 2:
The system performs self-monitoring and self-reporting of parameter status. The automatic comparison of actual versus required values and the generation of acoustic feedback signals eliminate the need for complex manual monitoring procedures, achieving high precision through relatively simple automated functionality.
4Manufacturing precision
If individual channel tuning is performed, then each channel can be optimized, but tuning process becomes multidimensional and tedious
Solution Approach 1:
The patent applies segmentation by providing separate acoustic feedback channels for different adjustment parameters and RF channels. Each parameter (resonant frequency, decoupling factor) and each RF channel has its own acoustic indication, allowing service personnel to systematically address each dimension independently while maintaining overall system optimization.

AI summary
A method for signaling a tuning of an adjustment parameter of an antenna coil arrangement of a magnetic resonance tomograph includes detecting a deviation between an actual adjustment value of at least one adjustment parameter and a required adjustment value of the at least one adjustment parameter. As a function of the deviation, an acoustic and/or a mechanical signal is output in real time to an operator. A device for signaling a tuning of an adjustment parameter of a coil arrangement of a magnetic resonance tomograph, and a magnetic resonance tomograph operating according to the method and/or containing the device are described.
