摘要： A system, and method for using magnetic resonance imaging to increase the accuracy of electro-physiologic procedures is disclosed. The system in its preferred embodiment provides an invasive combined electro-physiologic, an imaging antenna catheter (1) which includes an RF antenna (3) for receiving MR signals, and diagnostic electrodes (11) for receiving electrical potentials. The combined electrophysiology, and imaging antenna catheter (1) is used in combination with an MR imaging scanner to guide, to provide visualization during electro-physiologic diagnostic or therapeutic procedures.

摘要： The invention describes a system, method, and means for an MRI guidewire that can be visible on an MRI; can act as an antenna, and receive MRI signals from surrounding subject matter; and can allow the use of multiple interventional tools without removal of the guide wire from a subject. The antenna (106) extends beyond probe shaft (105) at distal end (109). The probe shaft (105) has a core (101), first electric (102), shield (103), and second dielectric (104).
