Portable Radiographing Device Barcode Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable radiographing devices lack effective patient identification systems, leading to potential misidentification during imaging, especially when patient information is not properly recorded or accessed.
Innovation Solution
Incorporating a patient identification information reading unit within the radiographing device to read and verify patient identification information against stored examination information, with a notification system to alert operators of any discrepancies, ensuring accurate patient-image association.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a bar code reader is used to read patient identification information, then patient identification can be obtained, but misidentification cannot be prevented when patient information is not properly recorded or the acquisition is forgotten
Solution Approach 1:
The system reads patient identification information from a barcode, then automatically checks this read information against the stored examination information in the radiographing device. This feedback mechanism compares the two data sets and generates an alert when they do not match, ensuring that even if patient information was not properly recorded or acquisition was forgotten, the system will detect the discrepancy and prevent misidentification.
Solution Approach 2:
The system performs the checking of patient identification information against examination information before the imaging process begins. By conducting this verification in advance, the system ensures that correct patient identification is confirmed prior to image acquisition, preventing misidentification from occurring in the first place.
2Loss of information
If a control device is used to store examination information, then patient information can be stored and managed, but the device becomes large and heavy requiring significant labor to move
Solution Approach 1:
The system combines the examination information storage capability directly into the radiographing device itself, merging previously separate functions (storage unit and radiographing device) into a single integrated unit. This eliminates the need for a separate control device, reducing overall system weight and complexity while maintaining the ability to store and manage patient examination information locally.
Solution Approach 2:
The radiographing device is designed to perform multiple functions: it can store examination information, read patient identification information via barcode scanner, check the consistency of this information, generate alerts for mismatches, and perform imaging. This multi-functional design eliminates the need for separate dedicated control devices, reducing weight and improving portability.

Implementation Method 1
an image acquisition unit configured to receive radiation that has passed through an examination target and acquire an image of the examination target
Data Source
AI summary
A radiographing device includes an image acquisition unit that receives radiation that has passed through an examination target and acquires an image of the examination target, a storage unit that stores examination target information, a reading unit that reads identification information assigned to an examination target, a checking unit that checks the stored examination target information and the read identification information against each other, a notification unit that makes a notification of information about a result of the checking, and a storage unit that, based on the result of the checking, stores the image of the examination target and the read identification information in association with each other.
