PROBE AND COIL FIXED THERETO FOR ESTABLISHING THE SPATIAL LOCATION OF A PROBE BODY AND A METHOD OF FIXEDLY POSITION A MAGNETIC GENERATING MEANS TO A PROBE BODY AND A SYSTEM FOR OBTAINING GEOMETRICAL DATA RELATED TO A CAVITY

摘要

Disclosed is a probe for obtaining geometrical data related to a cavity, the probe comprising a probe body comprising a first coupling means; at least one magnetic field generating device comprising a support member and a means for generating a magnetic field; wherein said means for generating a magnetic field being connected to the support member so as to fix a position of said means for generating a magnetic field relative to said support member and wherein said support member comprises a second coupling means configured to engage the first coupling means so as to connect the at least one magnetic field generating device to said probe body.;Thereby is achieved to improve positional accuracy of geometrical data related to an internal surface of a cavity.
