A calibration method includes receiving magnetic field values, which are generated by a plurality of real magnetic transmitters and are measured at multiple positions on a grid in a region containing a magnetic field perturbing element. Approximate locations of the real magnetic transmitters are received. Using the approximate locations, a respective plurality of imaginary magnetic sources is characterized inside the field perturbing element. Using the measured magnetic field values, the approximate locations, and the characterized imaginary sources, there are iteratively calculated (i) actual locations of the real and imaginary magnetic sources in the region, and (ii) modeled magnetic field values that would result from the real and imaginary magnetic sources at the actual locations. Using the calculated locations, and the modeled magnetic field values at the multiple positions on the grid, a magnetic field calibration function is derived for the region.

An apparatus includes a body, an upright member, a frame, and a plurality of field generating elements. The body is configured to be positioned between a patient's back and a backrest of a chair. The upright member extends upwardly from the body. The frame has a curved configuration configured to partially surround a patient's head. The field generating elements are configured to generate an electromagnetic field around a patient's head partially surrounded by the frame.
