Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing medical imaging technologies expose both the examination object and the observer to high radiation doses due to standardized recording rates that do not account for individual visual processing capabilities, leading to health risks and procedural challenges.

Innovation Solution

Adapt the provision of medical image data and its graphical display based on an observer's perception parameters, including temporal, spatial, and light-specific features, to optimize recording and processing parameters such as frame rate, spatial resolution, and image contrast, ensuring the data remains within the observer's visual limitations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high recording rates (e.g., 30 Hz or 60 Hz) are used to ensure fluid perception of image sequences, then visual perception quality is improved, but radiation dose exposure to the examination object and observer increases

Engineering Contradiction:

Improvevisual perception qualityVSAvoidradiation dose

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts the recording rate parameter based on the measured perception parameters of the observer. Instead of using fixed high recording rates, the system modifies this parameter to match individual visual capabilities, thereby reducing radiation exposure while maintaining adequate visual perception quality

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The recording rate is made dynamic and adaptable rather than static. The system continuously measures the observer's perception parameters and adjusts the recording rate in real-time, allowing the imaging system to optimize between visual quality and radiation dose based on current observer capabilities

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If standardized recording protocols with predefined recording rates are used, then device operation is simplified, but individual visual limitations of observers cannot be accommodated

Engineering Contradiction:

Improveprotocol simplicityVSAvoidadaptation to individual perception

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system performs self-adjustment by automatically measuring the observer's perception parameters and configuring the recording rate without requiring manual intervention. The observer simply views test patterns, and the system autonomously determines optimal settings, combining simplicity with personalization

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system incorporates feedback loops where the observer's visual response to test patterns is measured and used to adjust recording parameters. This closed-loop approach enables the system to adapt to individual perception characteristics while maintaining ease of operation through automated control

Inventive Principle:

Principle #23Feedback

AI summary

A method for provision of a graphical display of medical image data of an examination object includes acquiring a perception parameter of an observer. The perception parameter characterizes a visual limitation of the observer. The method includes providing the medical image data using a medical imaging device, and providing the graphical display of the medical image data using a display unit. The providing of the medical image data and/or the providing of the graphical display of the medical image data is adapted as a function of the perception parameter.
