Modality Editing Authority via Patient Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical imaging systems where multiple technicians can operate multiple modalities using tablet terminals, there is a risk of misidentifying the modality intended for a patient's examination, leading to incorrect operations.
Innovation Solution
A medical information management system that authenticates patients using tablet terminals, assigns editing authorities based on patient authentication data, and ensures that only authorized terminals can edit setting information for the correct modality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tablet terminals are allowed to operate multiple modalities, then operational flexibility and technician mobility are improved, but the risk of modality misidentification and incorrect operations increases
Solution Approach 1:
The system performs preliminary authentication of the patient before allowing terminal operations on the modality. The medical information management device authenticates patient information in advance and issues editing authority tokens to authorized terminals, ensuring that only authenticated users can operate the correct modality for the scheduled patient examination.
Solution Approach 2:
The modality provides feedback by transmitting its identification information to the medical information management device, which then verifies whether the terminal has proper editing authority for that specific modality. This feedback mechanism prevents unauthorized operations by confirming the match between the terminal's authenticated patient and the modality's scheduled patient.
2Reliability
If one tablet terminal is associated with one modality, then modality identification accuracy is maintained, but technician mobility and operational flexibility are restricted
Solution Approach 1:
The medical information management device serves as a universal authentication authority that manages editing authority for multiple modalities across multiple terminals. Instead of binding specific terminals to specific modalities, the system allows any authenticated terminal to operate any modality by verifying the terminal's editing authority token against the modality's scheduled patient information.
3Adaptability or versatility
If editing authority is granted to multiple terminals for the same patient, then operational flexibility is improved, but the complexity of authority management increases
Solution Approach 1:
The medical information management device acts as an intermediary that centralizes the management of editing authority for multiple terminals. Instead of each modality independently managing authority for multiple terminals, the management device issues and validates editing authority tokens, simplifying the overall authority management architecture while allowing multiple terminals to access the same patient's modality operations.
Data Source
AI summary
A medical information management device of an embodiment includes processing circuitry. The processing circuitry is configured to acquire patient authentication data for identifying a patient from a terminal device managed by a user, to authenticate that the patient is a user of a medical image diagnostic device on the basis of the patient authentication data, and to give the terminal device an editing authority to edit setting information on the patient set to examine the patient by the medical image diagnostic device on the basis of a result of the authentication.
