Single axis sensor (SAS) with Hall sensor using external magnet |
| abstract |
A catheter-based tracking system is provided. A catheter-based tracking system includes one or more magnetic field generators and a processor. One or more magnetic field generators located adjacent to the magnetic resonance imaging (MRI) system 40 are configured to apply an alternating current (AC) magnetic field. The processor has received a signal from the SAS to receive a signal responsively responsive to an AC magnetic field at a single axis sensor (SAS) 51 attached to a distal end of a catheter 50 inserted into a patient's organ. From a Hall effect sensor attached to the distal end of the catheter, a direct current (DC) magnetic field sensing component of a magnetic resonance imaging (MRI) system is calculated to determine the direction of the distal end based on the signal. And configured to calculate a roll angle of the distal end within the organ based on the receiving direction and the sensing component of the DC magnetic field. [Selection diagram] Fig. 1 |
