SYSTEMS AND METHOD FOR AUTOMATICALLY DETECTING AN MRI ENVIRONMENT FOR PATIENT IMPLANTED WITH MEDICAL DEVICE

摘要

Methods, medical devices, and magnetic resonance imaging (MRI) systems are provided. A patient implanted with a medical device is exposed to a time-varying magnetic field having a signature, thereby inducing mechanical vibrations in at least one component of the medical device. A vibrational characteristic of the mechanical vibrations induced in the component(s) is detected. The vibrational characteristic is analyzed, and the signature of the magnetic field is identified based on the analyzed vibrational characteristic. The medical device is automatically switched from a first operational mode to a second operational mode when the signature is identified.

1. A method of automatically identifying a signature in a time-varying magnetic field generated by a magnetic resonance imaging (MRI) device, comprising:
exposing a patient to the magnetic field, thereby inducing mechanical vibrations in at least one component of a medical device implanted in the patient; detecting a vibrational characteristic of the mechanical vibrations induced in the at least one component; analyzing the vibrational characteristic; and identifying the signature of the magnetic field based on the analyzed vibrational characteristic.
