METHOD AND APPARATUS FOR OBTAINING POSITION DATA RELATING TO A PROBE IN THE EAR CANAL |
摘要 |
A method for obtaining position data relating to a probe in the ear canal whereby a probe is inserted into the ear canal, the method further comprising the steps of: - determine the distance from the distal portion of the probe to at least one point of the internal circumferential surface of the ear and/or ear canal, - obtaining position data using first transducing means associated with the distal portion of the probe and second transducing means fixed relative to the head of the person, where the first transducing means is transmitting a magnetic field, and the second transducing means are detecting the magnetic field generated by the transmitter. The invention also relates to an apparatus for obtaining position data relating to a probe in the ear canal. |
