RFID Tagged Image Plate Control for Medical Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical imaging, there is a challenge in ensuring that image information from image plates is correctly associated with the intended patient or doctor, and that image plates are inserted and read in the correct order, particularly in series, to prevent mixing and misinterpretation of images.
Innovation Solution
The use of a tag with remotely readable and writable information on image plates or their transport means, which contains position and control information, allowing the system to deliver image data to the correct destination and maintain correct order, even if plates are inserted arbitrarily, by using technologies like RFID or barcodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image plates are manually managed and read in a fixed order, then image information can be associated with patients, but image plates may become mixed up and reading efficiency is reduced
Solution Approach 1:
The system performs preliminary actions by writing control information to the image plate tag during imaging, including patient identification and destination information. This preliminary tagging allows the reading device to automatically process plates in any order without manual intervention, resolving the contradiction between reliable association and reading efficiency
Solution Approach 2:
An intermediary tag system is introduced between the image plate and the reading device. The tag contains control information that mediates the automatic association of image data with patient records, eliminating the need for manual plate management while ensuring correct information association
2Reliability
If the reading device is reserved in advance for a doctor, then image information can be delivered to the correct doctor, but the reservation system becomes complex and may fail if reservation time is insufficient
Solution Approach 1:
The system implements self-service by embedding destination information directly in the image plate tag. The reading device automatically reads this control information and delivers images to the correct doctor without requiring manual reservations or complex scheduling systems
Solution Approach 2:
The reservation function is extracted from the reading device and transferred to the image plate tag system. Control information about destination and timing is taken out from the device reservation system and embedded in the portable tag, simplifying the overall system
3Reliability
If multiple image plates are read in a series, then complete patient imaging can be achieved, but plates may get into wrong order making reconstruction impossible
Solution Approach 1:
The system uses feedback mechanisms where the reading device reads control information from each plate's tag, determines the correct sequence automatically, and processes plates in the proper order. This feedback loop ensures correct ordering without requiring manual intervention or complex operational procedures

AI summary
A medical imaging system includes at least an image plate, X-ray device for producing an image of an object on said image plate, and a reading device for reading image information held by the image plate. In connection with the image plate there is a tag containing information for controlling the arrangement in such a manner that when the arrangement has read the information in the tag the arrangement is adapted to perform at least one operation controlled by the information read.
