Supersonic AIXPLORER MultiWave Bedienungsanleitung Seite 18

Avoid metallic objects that include steel or iron between the tracking
transmitter and receiver since they may affect the accuracy of the tracking
device. If in doubt, please contact your technical support.
Don't put the transmitter too close to walls containing metallic
components, it could affect the accuracy of the tracking.
Patients with cardiac pacemakers shall not be treated with the Fusion/
Navigation feature.
During and after the registration, do not move the transmitter nor the
patient during the following session. For each session or in the event of
a patient shift or transmitter movement, the registration procedure has to
be repeated, unless "movement correction" is activated through the use
of omniTRAX™ CT or MR.
When one of the the needle guidance tools (VirtuTRAX™ or eTRAX™)
is enabled on the Ultrasound device while in Navigation or Virtual Mode,
it displays a corresponding virtual biopsy line in the 2nd modality image.
These guidelines are intended to be used as an additional orientation tool
but must not be used without considering the real-time ultrasound biopsy
line display. In particular it should not be considered during percutaneous
procedures as it may not reflect the real-time situation.
The Virtual Needle length is defined by the distance between the sensor
and the needle tip. Calibrate the needle to acquire the right length or enter
it manually. The measure is considered in cm.
