MAGNETIC RESONANCE IMAGING GUIDEWIRE PROBE

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...

More Information
Summary: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). L'invention concerne un système, un procédé et un moyen pour un fil-guide d'IRM pouvant être visible sur une IRM, pouvant faire office d'antenne et recevoir des signaux IRM provenant de la matière du sujet environnant et permettant l'utilisation de multiples outils d'intervention sans qu'il soit nécessaire d'enlever le fil-guide du sujet.
