Medical Imaging System Operation Authority Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical image imaging systems, there is a challenge in ensuring that only authorized personnel can operate the imaging equipment during the imaging process, particularly when multiple users share the same modality, to prevent unintended changes to patient information and ensure safe operation.
Innovation Solution
A medical image imaging system that determines the progress in the imaging workflow and dynamically assigns or removes operation authority to user terminals based on predefined stages, ensuring that only authorized users can perform operations during specific phases of the imaging process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operation authority is restricted to prevent unintended changes, then safety and integrity of patient information is improved, but ease of operation deteriorates due to limited access
Solution Approach 1:
The system dynamically changes operation authority based on workflow progress. The determination unit tracks imaging workflow stages, and the assignment unit grants or revokes operation authority accordingly. This dynamic approach ensures that only authorized personnel can operate during imaging while automatically allowing uninvolved technicians to access information after imaging completes, thus maintaining both safety and ease of operation.
2Productivity
If multiple users can operate the modality simultaneously, then productivity is improved, but reliability deteriorates due to potential interference with patient information
Solution Approach 1:
The system applies different operation permissions to different users based on their involvement in the imaging workflow. The determination unit identifies which users are involved in current imaging, and the assignment unit grants operation authority only to those specific users while restricting others. This localized permission approach allows multiple users to work simultaneously on different tasks without interfering with patient information integrity.
3Reliability
If operation authority is dynamically assigned based on workflow progress, then reliability is improved by ensuring authorized access, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The system uses the existing workflow management functionality to automatically determine imaging progress and manage operation authority. The determination unit leverages the modality's built-in workflow tracking, and the assignment unit automatically grants or revokes permissions based on workflow stages. This self-service approach minimizes additional complexity by reusing existing system capabilities rather than introducing separate manual authorization processes.

AI summary
A medical image imaging system according to an embodiment includes a processing circuitry. The processing circuitry determines a progress in a workflow related to imaging of a subject by a medical image imaging apparatus. The processing circuitry assigns an operation authority for the medical image imaging apparatus to one user terminal among a plurality of user terminals in accordance with the determined progress.
