Abstract:
A guidewire (100) for use with interventional magnetic resonance imaging has a guidewire body (102) having a distal end and a proximal end and reserving a space therein, a dipole antenna (108) disposed in the space reserved within the guidewire body, the dipole antenna being adapted to be electrically connected to a signal processing system through a first signal channel (110) through the proximal end of the guidewire body, and a loop antenna (112) disposed in the space reserved within the guidewire body toward the distal end of the guidewire body, the loop antenna (112) being adapted to be electrically connected to the signal processing system through a second signal channel (114) through the proximal end of the guidewire body. The dipole antenna and the loop antenna are each constructed to receive magnetic resonance imaging signals independently of each other and to transmit received signals through the first and second signal channels, respectively, to be received by the signal processing system. An interventional magnetic resonance imaging system includes an active guidewire.
