Tests Show Fujitsu UHF RFID Linen Tags Are Suitable for Use in MRI Systems
Fujitsu Frontech North America has announced that tests conducted by magnetic resonance imaging (MRI) test facility Magnetic Resonance Safety Testing Services (MRSTS) on several of its ultrahigh-frequency (UHF) RFID linen tags show that they are acceptable for use in association with all types of MRI systems operating at 1.5 Tesla and 3 Tesla.
Tests were performed on Fujitsu's WT-A53x x and WT-A52x families of UHF RFID linen tags. Using state-of-the-art MRI testing facilities, the company reports, MRSTS was able to characterize both the effects of worst-case MRI exposures and possible MRI-related issues, such as magnetic field interactions, heating and artifacts (imaging errors) using its sophisticated techniques. Based on the results, MRSTS recommended the labeling "MR Conditional" for 1.5T and 3.0T MRIs—the highest rating that can be applied for an RFID device, according to Fujitsu. The results of these tests conducted on the Fujitsu tags have been posted at MRISafety.com .University of Southern California's Keck School of Medicine. "We were very impressed with the Fujitsu linen RFID tag. The construction of the tag and selection of internal components make it ideal for use in hospital garments and linens used in and around MRI systems," Shellock, said in a prepared statement. "We were also surprised by the relatively small image artifact generated by the tag. The measured maximum image artifact of 2 millimeters under worst case MRI conditions will substantially reduce the impact on the diagnostic use of MRI."
The WT-A533 is a rugged tag designed for use in a multitude of applications, according to Fujitsu, including health-care garments, scrubs and flat linens. The tag is designed to withstand industrial laundry applications and can survive hundreds of washings under very harsh washing conditions. Confirmation by independent testing performed by MRSTS expands the product's usability to include sheets and gowns that are actually present inside of the MRI equipment, the company notes.
Vizinex RFID and Brady SmartID Release Aerospace Tags
RFID tag maker Vizinex RFID and Brady SmartID, a provider of solutions for tracking assets and aircraft parts, have announced new RFID tags designed for the aerospace industry. The new Rigid RFID series of tags features 2 kilobits of user memory and meet the ATA Spec-2000 CH 9 Rev 2016.1 requirements for commercial aircraft, according to the two companies.
The portfolio includes the Stik and the Nickl. Measuring 36.4 millimeters by 7.0 millimeters by 4.4 millimeters (1.4 inches by 0.3 inch by 0.2 inch), the Stik is a mount-on-metal tag with a slim profile and an average read range of 2.35 meters (7.7 feet). The Nickl is a mount-on-metal tag designed for smaller parts that measures 14.0 millimeters by 14.0 millimeters by 5.8 millimeters (0.6 inch by 0.6 inch by 0.2 inch) and has an average read range of 1.5 meters (4.9 feet). The companies have declined to identify the RFID chip used in either model. Brady SmartID will be selling the tags.
