Solution Overview

Problem

MRI examinations are often unpleasant and stressful for patients due to loud noises and long durations, with conventional media signals failing to match the examination duration and content, leading to patient irritation and discomfort.

Innovation Solution

An MRI system that uses a generative AI system to generate personalized media signals based on patient-specific examination parameters, including audio and video tracks, synchronized with the MRI procedure to provide a tailored distraction and improve patient comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional media signals are played during MRI examination, then patient distraction is provided, but the media signal cannot be perceived undisturbed due to high gradient coil noise

Engineering Contradiction:

Improvepatient discomfort from noiseVSAvoidgradient coil noise

Core Design Contradiction:

Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent synchronizes the media signal playback with the gradient coil activation cycles, converting the harmful noise into a rhythmic pattern that matches the media signal. The media signal is played during periods when gradient coils are less active or in synchronization with their activation, transforming the chaotic noise into a structured audio experience that patients can perceive clearly.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent implements periodic playback of media signals that aligns with the periodic nature of gradient coil activation during MRI sequences. By matching the rhythm and timing of media signal playback with the examination protocol's gradient pulse patterns, the system creates predictable audio intervals that patients can follow without confusion or distortion.

Inventive Principle:

Principle #19Periodic action

2Ease of operation

If fixed-duration media signals are used, then simple playback is achieved, but the media signal duration does not match the variable examination duration causing patient irritation

Engineering Contradiction:

Improvemedia signal playback simplicityVSAvoidmedia signal duration adaptation

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic duration adjustment of media signals based on the actual examination protocol. The system receives the examination schedule from the MRI control system, calculates the total examination duration including all sequences and pauses, and automatically adjusts the media signal playback duration to match. This allows the same simple playback mechanism to adapt to variable examination lengths without manual intervention.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent establishes a feedback loop where the media signal playback duration is continuously adjusted based on real-time examination progress. The system monitors the actual examination timeline, compares it with the media signal duration, and dynamically synchronizes their endings to ensure the media signal concludes at the same time as the examination, preventing patient irritation from premature or extended playback.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If generic media signals are played, then broad applicability is achieved, but the content does not coordinate with the specific examination and patient needs

Engineering Contradiction:

Improvemedia signal content relevanceVSAvoidmedia signal selection and customization system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent adjusts key parameters of the media signal based on examination characteristics and patient data. The system modifies playback volume, audio track selection, video content type, and timing parameters according to the examination protocol duration, gradient coil noise patterns, and patient profile (age, anxiety level, previous experience). This parameter-based customization allows generic media libraries to be adapted to specific examination contexts without requiring complex content creation for each scenario.

Inventive Principle:

Principle #35Parameter changes
