INTRABEAM Water Phantom

Version 6.2

G-30-1767-en

•

Fix the setting of the Z position by actuating the locking lever on the ad-
justing knob for the Z axis.

•

Search for the exact center position for the probe tip via the measuring
window in the X and Y coordinate axes in succession:

NOTE

If the probe tip is bent out of tolerance while being inserted in the water
phantom, the XRS 4 will no longer be able to emit radiation and the quality
assurance steps must be repeated.

•

Carefully insert the XRS 4 into the XRS mount in the rotary feedthrough.

•

Make sure that the probe tip does not touch the measuring chamber
while adjusting the positioning unit.
