A magnetic position and orientation determining system uses magnetic fields, desirably including uniform fields from Helmholtz coils positioned on opposite sides of a sensing volume and gradient fields generated by the same coils. By monitoring field components detected at the probes during application of these fields, the position and orientation of the probe in the field can be deduced. A representation of the probe can be superposed on a separately acquired image of the subject to show the position and orientation of the probe with respect to the subject.
Apparatus for determining position of an object comprising: (a) magnet means for generating a plurality of different magnetic fields in a sensing volume, each said field having at least one component having a magnitude which is quasilinear with respect to distance in a reference direction within sai
Apparatus for determining position of an object comprising: (a) magnet means for generating a plurality of different magnetic fields in a sensing volume, each said field having at least one component having a magnitude which is quasilinear with respect to distance in a reference direction within said sensing volume, said magnitude being non-zero in at least some locations within said sensing volume; (b) control means for actuating said magnet means to generate said fields in a predetermined sequence; (c) a sensor connected to the object and movable within said sensing volume, and adapted to detect magnetic field components in at least two different local directions relative to the sensor and provide separate data representing each said component; and (d) calculation means for determining the position of said sensor from said data representing said magnetic field components detected during generation of said fields.
