Abstract
The disclosure is directed to techniques in which magnetic resonance imaging (MRI) is coordinated with the operation of an implantable medical device (IMD). By using an IMD to sense conditions, MRI can be improved because the sensed conditions can accurately define timing for application of electromagnetic radiation bursts. Moreover, by applying stimulation pulses specifically to coordinate the electromagnetic radiation bursts, the MRI may also be improved.
Claims17
A method comprising:
- receiving, with a magnetic resonance imagining (MRI) device, information from an implantable medical device (IMD) regarding sensed electrical events measured by the IMD;
- defining, with the MRI device, timing of the electromagnetic radiation bursts based on the information received from the IMD regarding sensed electrical events measured by the IMD;
- and
- applying, with the MRI device, electromagnetic radiation bursts to a patient within which the IMD is implanted based on the defined timing.

A device comprising:
- a telemetry unit to receive information from an implantable medical device (IMD) regarding sensed electrical events measured by the IMD;
- a control unit that defines timing of electromagnetic radiation bursts of a Magnetic Resonance Imaging (MRI) based on information received from the IMD regarding sensed electrical events measured by the IMD;
- and
- electromagnetic radiation source of the MRI that applies electromagnetic radiation bursts to a patient within which the IMD is implanted based on the defined timing.
