发明名称 Device for Cancellation of Large Magnetic Susceptibility Artifacts in Magnetic Resonance Imaging of Patients with Pacemakers and Implantable Cardiac Defibrillators
摘要 The present invention is directed to a system and method for reducing large magnetic artifact susceptibility in magnetic resonance imaging. The present invention is used to maximize cancellation of the magnetic field distortion cremated when objects with high variations in magnetic susceptibility are placed in a uniform magnetic field. Particularly, the present invention reduces the magnetic resonance imaging artifact produced by pacemakers and internal cardiac defibrillators in order to maximize the diagnostic image quality in the region surrounding these devices.

主权项 1. A system for cancelling an artifact in magnetic resonance imaging comprising: a solenoid electromagnet having a coil and said solenoid electromagnet is configured to be positioned adjacent to a source of the artifact; and, a non-transitory computer readable medium programmed to determine adjustments to the solenoid electromagnet to reduce the artifact.
