Exposure validation
Exposure is allowed (the interlock relay is closed) if the ceiling stand is standing still and is
operating properly (not in an error state).
4.3.5.3 Tracking
There are four different default tracking distances in the system, two for each tracking techni-
que, i.e.
Wall stand
and
Table Tracking Technique
.
The two types for both tracking techniques are against vertically and horizontally placed
detectors.
These default distances are set during installation of the system. Which default tracking dis-
tance that is used depends on which tracking technique that is chosen on the tube holder
and the angle of the X-ray tube.
Wall stand
or
Table Tracking
is selected from the display and
an image at the display shows if the wallstand or the table is selected.
The synchronization button below the display, indicates the status.
CAUTION!
The user shall control if the tracking is activated, or not. This is done by checking if
the synchronization button, at the wallstand or the OTC, is lit.
The light indication can be flashing or constant. The light indication will be constant if the sys-
tem is in the correct position for tracking (normally default tracking distance) and flashing if it
is not. If the light indication is flashing, there are two ways to get the system to its correct
tracking distance.
1. Move wall stand or table (depending on which tracking is activated).
2. Push and hold the synchronization button at the wall stand or at the OTC.
Tracking movement is performed as long as the movement is activated on the tracked stand,
i.e. wall stand or table, the ceiling stand will move to find the correct distance and then contin-
ue to track at that distance.
If the tracked stand is already in the desired position, the synchronization button at the wall-
stand or at the OTC can be pushed and held to get the system to move to the correct
position.
When the system has reached the correct distance for tracking, any manual movement on
the tube holder (Z-direction) will change the tracking distance to the distance it is placed on
when stopping the tube holder movement.
Moving the tube angle will affect the correct distance for tracking if it is moved across the -45
or 45 degree angle.
The correct distance for tracking is then set to the default tracking distance, since it has
changed between horizontally and vertically placed detector.
Except for tracking against a vertically placed detector on the wallstand, tracking is always
prohibited downward below the safety zone.
