Claim 0:
1. An apparatus for calibrating a probe that includes an image sensor and a magnetic field sensor, the apparatus comprising:
a magnetic field generator being configured to generate at least one magnetic field having a predefined direction in alignment with a jig;
the jig being configured to hold the probe such that the axes of the magnetic field sensor are substantially aligned with the respective axes of the magnetic coordinate frame based on the predefined direction of the magnetic field;
an optical target aligned with the jig, based on a central alignment feature, so that the image sensor in the probe is able to capture an image of the optical target while the probe is held in the jig, the optical target being configured to be rotated around the central alignment feature; and
processing circuitry configured to receive from the probe a signal output by the magnetic field sensor in response to the at least one magnetic field and the image captured by the image sensor while the probe is held in the jig, and to calibrate an alignment of the image sensor relative to the magnetic field sensor responsively to the received signal and the received image.
