1. An arrangement for making a magnetic field measurement of a measurement object, comprising:
a magnetic field sensor configured to measure a magnetic field of a measurement object;
a measurement mechanism that positions said magnetic field sensor at a first position;
a plurality of detectable reference indentifiers configured for placement on said measurement object;
a position sensor that interacts with said detectable reference identifiers to calibrate a spatial position of said position sensor, said position sensor being arranged at a second position on said measurement mechanism; and
a processor that, based on knowledge of said first position and said second position, associates a spatial position relative to the measurement object with each magnetic field strength of the measurement object that is measured by the magnetic field sensor.
