Automated Patient Authentication System for Radiographic Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radiographic imaging systems, the task of patient authentication and medical device control is burdensome for examination operators, as they need to manually verify patient identities and manage device operations, leading to inefficiencies in clinical examinations.
Innovation Solution
A patient authentication system that includes a bio-information acquisition unit, identification information acquisition unit, authentication unit, and device control unit, which uses a reference database to automatically authenticate patients based on pre-captured bio-information and identification data, thereby automating the control of medical devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual patient authentication and device control methods are used, then examination operators can verify patient identities and manage device operations, but the workload and time consumption increase significantly
Solution Approach 1:
The patent replaces the mechanical manual authentication process with an automated biometric recognition system. The biometric acquisition unit captures physiological features (fingerprint, facial recognition, iris, or voice), and the authentication unit automatically compares these against stored reference data in the database, eliminating the need for manual verification by examination operators while maintaining high authentication accuracy.
Solution Approach 2:
The system enables self-service authentication where patients automatically provide their biometric information through the biometric acquisition unit. The system autonomously performs authentication without requiring operator intervention, and automatically controls the medical device based on authentication results, making the process self-acting and reducing human workload.
2Productivity
If automated biometric authentication is implemented, then authentication speed and efficiency improve, but system complexity increases
Solution Approach 1:
The authentication system is divided into distinct functional modules: a biometric acquisition unit for capturing physiological data, a database for storing reference information, an authentication unit for comparing and verifying data, and a device control unit for operating medical equipment. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability despite the increased automation capability.
3Reliability
If multiple biometric recognition methods are provided, then authentication accuracy and security improve, but device complexity and cost increase
Solution Approach 1:
The biometric acquisition unit is designed with multi-functionality to support multiple authentication methods including fingerprint recognition, facial recognition, iris recognition, and voice recognition. This universal design allows the system to adapt to different patient needs and preferences while maintaining a unified system architecture, balancing the need for high security with operational flexibility.

AI summary
A patient authentication system is provided with: an authentication unit configured to authenticate a subject based on a reference database, a patient authentication bio-information acquired by a patient bio-information acquisition unit, and patient identification information acquired by a patient identification information acquisition unit, the reference database storing patient reference bio-information acquired in advance as bio-information to be referred to when authenticating the patient and patient reference identification information to be referred to when authenticating the patient in association with each other; and a device control unit configured to perform control of a medical device based on an authentication result which is a result of authentication by the authentication unit.
