Abstract
In some examples, a method including detecting, via processing circuitry, an induced voltage in at least one of an electrode or a lead conductor of an implantable medical device, wherein the induced voltage is induced in the at least one of the electrode or the lead conductor of the implantable medical device by a radio frequency (RF) field generated by a magnetic resonance imaging (MRI) scanner; and modifying, via the processing circuitry, an MRI scan based on the detected induced voltage.
Claims23
A method comprising:
- detecting, by first processing circuitry of an implantable medical device disposed completely within a patient, an induced voltage in at least one of an electrode or a lead conductor of an implantable medical device, wherein the induced voltage is induced in the at least one of the electrode or the lead conductor of the implantable medical device by a radio frequency (RF) field generated by a magnetic resonance imaging (MRI) scanner;
- predicting a temperature of the at least one of the electrode or the lead conductor of the implantable medical device based on the detected induced voltage;
- transmitting, by the implantable medical device, information indicative of the induced voltage to second processing circuitry;
- and
