The intensity of the magnetic field generated by the position sensor transmitter becomes
lower as the measurement
point is moved away from the transmitter.
The position sensor
receiver must be within the spherical range from 21 cm to 76 cm from the center of the
position sensor transmitter as shown in figure 17-4. In addition, the position sensor receiver
must be within the front hemisphere of the magnetic field, which is one of the two
hemispheres defined by the positive and negative directions on the x-axis, in order to
assure the accuracy of the positional data. If the position sensor receiver is moved across
the front and rear hemispheres during data acquisition, image reconstruction becomes
impossible.

Figure 17-4 Position sensor transmitter
The position sensor receiver is attached to a transducer using the dedicated attachment as
shown in figure 17-5 (the transducer shown in the figure is the 375AT). Refer to the
relevant operation manual for the procedure for attaching the position sensor receiver.
