MRI PHASE VISUALIZATION OF INTERVENTIONAL DEVICES

摘要

Imaging a device in a magnetic resonance imaging system includes inserting a device having a conductive coil assembly thereon into a subject, obtaining a magnetic resonance image of the subject that includes signal phase variations, determining a position of the device based on discontinuities in the signal phase variations, and displaying an image representation of the device superimposed on a reference image based upon the determined position.
