Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Magnetic resonance imaging (MRI) workflows are inefficient due to the complexity of preparation steps and the need for manual input of information, which can lead to errors and increased time and risk during patient examination.
Innovation Solution
A user interface and analysis module are integrated into the MRI system, providing guided instructions and feedback based on patient-specific information and selected examination protocols, ensuring that necessary equipment is connected in the correct order and that safety protocols are followed, such as suppressing metal artifacts, to streamline the imaging process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual input of examination information is used, then device complexity is reduced, but workflow efficiency deteriorates and error risk increases
Solution Approach 1:
The system automatically retrieves examination information from the HIS system without requiring manual input by operators. The analysis module autonomously processes this information to generate preparation steps and equipment connection instructions, making the system self-sufficient in information gathering and workflow management.
Solution Approach 2:
The analysis module continuously monitors the examination protocol and provides real-time feedback to the user interface, guiding operators through preparation steps and equipment connections. This feedback mechanism ensures that the correct equipment is connected in the proper sequence based on the specific examination requirements.
2Device complexity

The system automatically retrieves examination information from the HIS system without requiring manual input by operators. The analysis module autonomously processes this information to generate preparation steps and equipment connection instructions, making the system self-sufficient in information gathering and workflow management.
Solution Approach 2:
The analysis module continuously monitors the examination protocol and provides real-time feedback to the user interface, guiding operators through preparation steps and equipment connections. This feedback mechanism ensures that the correct equipment is connected in the proper sequence based on the specific examination requirements.
3Productivity
If guided instructions and feedback are provided, then workflow efficiency improves, but device complexity increases
Solution Approach 1:
The system divides the examination workflow into distinct segments: information retrieval from HIS, analysis of examination protocols, generation of preparation steps, and guidance on equipment connections. Each module handles a specific aspect of the workflow, making the overall complex system manageable through functional segmentation.
Solution Approach 2:
The analysis module acts as an intermediary between the examination protocol definition and the user interface. It translates the protocol requirements into actionable preparation steps and equipment connection instructions, mediating between the complex backend systems and the operator's needs.
4Reliability
If equipment connection order is enforced, then examination safety improves, but workflow flexibility deteriorates
Solution Approach 1:
The system determines and communicates the correct equipment connection sequence in advance, before the actual examination begins. Operators are guided to connect equipment in the proper order based on the analysis of the examination protocol, ensuring safety requirements are met before the examination starts.
Solution Approach 2:
The system dynamically adapts the equipment connection requirements based on the specific examination protocol being executed. Different protocols have different equipment requirements and connection sequences, and the system adjusts its guidance accordingly, providing flexibility within safety constraints.

AI summary
A magnetic resonance examination system is provided with a graphical user interface and an (software) analysis module. The analysis module is configured to analyze examination information, notably a selected examination protocol, for actions to be taken by the operator, such as connecting auxiliary equipment or radio frequency receiver coils to the magnetic resonance examination system. The analysis module supplies the actions to be taken to the (graphical) user interface at the proper instant before or during carrying-out the examination protocol. In this way the operator is guided and supported in the performance of the selected examination protocol. This improves the efficiency of workflow in performing one or more selected protocols. Preferably, the graphical user interface is provided inside the examination room and may be mounted on the gantry.
