The hospital is skeptical about the use of any type of RFID tag in linen. The reason for this is that all HF and most UHF laundry tag contain iron or even copper components in the antenna, which appear as metal threats and attach to the microchip itself. If such a label appears in an MRI scanner, the entire image may be blurred, which cause a very expensive and time consuming scanning may process to be redone. In some cases, the patient’s life may even be at risk.
Since any linen project may be present in the MRI room, the hospital cannot and should not use any label containing black or magnetized material. But this is good news! The Textile UHF tag from RFIDHY contains an antenna for non-ferrous materials. The first tests performed by Dutch hospitals have now been confirmed by other tests in hospitals in the United States and Austria. Images made from RFIDHY UHF laundry tag are even attached to men’s skin and do not display any artifacts (image changes). The same tests as any other known UHF and HF brands in the industry bring so many blurs/artifacts to images that make them useless to radiologists (the picture on the right side of the image below shows the so-called “susceptibility characteristics” “(SUSCEPTIBILITYARTEFACTS)). https://www.hy-smart.com/rfid-product/rfid-fabric-laundry-tags/
The RFIDHY UHF laundry tag laundry label complies with EPC Gen2 (EPC Global UHF Class 1 Generation 2). The tag does not contain any type of battery or power source and is inherently passive and cannot transmit RF signals independently. Labels cannot be magnetized and cannot maintain a permanent magnetic field. Due to its construction and material selection, RFIDHY UHF laundry tags have no effect on the magnetic fields associated with typical magnetic resonance imaging (MRI) systems and are safe and reliable when installed in close to or even used sheets and garments in typical MRI equipment. Dans. There is no ferromagnetic risk due to the heating of metal objects from MRI RF and the possibility of burns caused by current sensing or RF heating.
The picture shows the effect of a classic UHF tag and a metal threat antenna on an MRI image, rendering the image ineffective. The RFIDHY UHF laundry tag is not visible on such images and is ideal for use in the healthcare field. The bottom position is just a bubble. RFIDHY UHF laundry tag is the best choice for marking linen in the healthcare field!
