摘要：
An electromagnetic navigation device for guiding and tracking an interventional tool (40) within an anatomical region. The electromagnetic navigation device employs a guidewire (20) insertable into the anatomical region, and a hub (30) translatable and/or rotatable in conjunction with the interventional tool (40) relative to the guidewire (20). In operation, the guidewire (20) includes one or more guidance electromagnetic sensors generating guidance data informative of an electromagnetic sensing of a position and/or an orientation of the guidewire (20) relative to the anatomical region, and the hub (30) includes a tracking electromagnetic sensor (31) generating tracking data informative of an electromagnetic sensing of a position and/or an orientation of the hub (30) relative to the guidewire (20). Responsive to the electromagnetic sensing data, a navigation controller (76) controls a determination of a position and/or an orientation of the interventional tool (40) relative to the guidewire (20).
