RFID Tagged Computed Radiography Plates for Plate Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intra-oral dental computed radiography faces challenges with mismatching of information carrier plates and components, leading to errors and inefficiencies due to lack of reliable identification and tracking systems, especially in environments with shared scanners and multiple treatment rooms.
Innovation Solution
Implementing RFID tags with memory capabilities on flexible information carrier plates and license media for loading both permanent and temporary identification information, enabling secure tracking and access control within the computed radiography system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual tracking methods are used for information carrier plates, then the system is simpler to operate, but the reliability of plate identification and tracking deteriorates
Solution Approach 1:
The information carrier plate performs self-identification through an embedded identifier (such as RFID tag, barcode, or data matrix code) that automatically provides plate identification information to the system, eliminating the need for manual tracking while ensuring accurate and reliable plate identification throughout the imaging cycle
Solution Approach 2:
The manual mechanical tracking system is replaced with an automated electronic identification system using electromagnetic fields (RFID) or optical scanning (barcode/data matrix), which reads the embedded identifier on the plate to automatically track and identify the plate without human intervention
2Productivity
If multiple treatment rooms share the same scanner, then resource utilization improves, but the probability of plate mismatch increases
Solution Approach 1:
The system implements automatic feedback by reading the embedded identifier on each information carrier plate, retrieving the associated patient and treatment data from memory, and verifying the match before processing. This automated feedback mechanism prevents mismatches even when multiple treatment rooms share the same scanner
Solution Approach 2:
The embedded identifier on the information carrier plate serves as an intermediary that carries unique identification information, linking the physical plate to its corresponding patient and treatment data in the system's memory, ensuring accurate tracking through multiple treatment rooms and shared scanners
3Ease of operation
If no identification means are provided on plates, then the system is easier to manufacture, but the ease of operation deteriorates due to complex tracking requirements
Solution Approach 1:
The information carrier plate includes a self-identifying embedded identifier that automatically provides tracking information, making the system easier to operate without requiring complex manual tracking procedures, while the identifier integration during manufacturing adds minimal complexity to the production process

AI summary
A method for licensing a system for obtaining an X-ray image of a subject. The system employs flexible information carrier plates for computed radiography, which are exposed to X-rays and then scanned in a scanner. A license media is provided with a RFID transponder, which stores in its memory identification information referring to the system components as well as information referring to an amount of valid licenses available for use of the system components. When the identification information stored in the memory of the license media RFID transponder matches the identification information transmitted to the scanner by a processing and acquisition station the carrier plates are scanned automatically.
