Section 6-3
Volume Navigation Calibration Procedure
6-3-1 Purpose of this section
The Volume Navigation Calibration Procedure within the LOGIQ S8 is described in this section.
6-3-2 Overview
The Volume Navigation system is factory calibrated. However, small variations in the electromagnetic
sensors, sensor brackets and the probes themselves can create system-to-system variation. This
procedure is a means to do a system-specific calibration correction.
Note that the field calibration only applies to the specific type of probe (9L-D, ML6-15-D, C1-5-D, e.g.)
that is used. Therefore, it may be necessary to repeat this procedure for each probe type that a
customer owns.
6-3-3 Equipment
Use a phantom (optional) with distinguishable points that can be scanned from at least two directions
(top and side, e.g.). It is best to use a special “calibration phantom” (optional) that has target points in
the phantom (optional) and has been developed for this purpose. Note that the strings in many
phantoms (optional) are not a good choice because it is not easy to specify a particular point along the
string.
