    • A method and apparatus for ferrous object and/or magnetic field detection are provided. Embodiments can improve magnetic resonance imaging (MRI) safety and increase the safety of MRI facilities. Embodiments can detect a given magnetic field strength around a MRI machine and alert users to the field's presence. In an embodiment, the magnetic field warning system can rely on a single badge that warns its user. In another embodiment, the badge can utilize an RFID system. The RFID system can turn the badge on when it enters the MRI room and off when it leaves the MRI room. In another embodiment, a badge with a rechargeable battery and charger can be utilized with or without an RFID tag. The subject badges or other detection devices can be worn by a person, located on or near a ferrous object, embedded in clothing, or located in other positions convenient to a user.
    • 提供了一种用于铁物体和/或磁场检测的方法和装置。 实施例可以改善磁共振成像(MRI)的安全性并增加MRI设备的安全性。 实施例可以检测MRI机器周围的给定磁场强度,并且向用户提醒现场的存在。 在一个实施例中,磁场警告系统可以依靠警告其用户的单个徽章。 在另一个实施例中,徽章可以利用RFID系统。 当RFID系统进入MRI室时,RFID系统可以打开徽章,当离开MRI室时,它将被关闭。 在另一个实施例中,具有可充电电池和充电器的徽章可以在有或没有RFID标签的情况下使用。 主体徽章或其他检测装置可以由位于或接近有色金属物体的人佩戴,嵌入衣服中,或位于便于使用者的其他位置。
