According to the management efficiency of material storages, a design scheme of automatic management system is designed based on radio frequency identification devices. The hardware platform of the system is realized based on nRF2401 and embedded computer technology. The software design of each subsystem is achieved by using the middleware technology of radio frequency identification devices and embedded software development and database programming technology. The field trial experiments and the laboratory testing results indicate that the system can realize effectively the automatic identification and management of material storages. It can improve the operation efficiency and greatly enhance the automation level of material storages management and save the cost of management.

The objective of this study was to evaluate two issues regarding magnetic resonance imaging (MRI) including device functionality and image artifacts for the presence of radio frequency identification devices (RFID) in association with 0.3 Tesla at 12.7 MHz MRI and computed tomography (CT) scanning. Fifteen samples of RFID tags with two different sizes (wristband and ID card types) were tested. The tags were exposed to several MR-imaging conditions during MRI examination and X-rays of CT scan. Throughout the test, the tags were oriented in three different directions (axial, coronal, and sagittal) relative to MRI system in order to cover all possible situations with respect to the patient undergoing MRI and CT scanning, wearing a RFID tag on wrist. We observed that the tags did not sustain physical damage with their functionality remaining unaffected even after MRI and CT scanning, and there was no alternation in previously stored data as well. In addition, no evidence of either signal loss or artifact was seen in the acquired MR and CT images. Therefore, we can conclude that the use of this passive RFID tag is safe for a patient undergoing MRI at 0.3 T/12.7 MHz and CT Scanning.
