Page 5-7
The Wallstand has a detector holder with loading from the left side enabling the operator to
work from an optimal position at all times. Working with the Wallstand detector holder tilted,
will require additional operations to get the x-ray tube and the image receptor aligned (rotation
of the beta axis) due to the placing of the Wallstand.
A System installed in a room with similar size and with the components placed as described in
Figure 5-3 , usually requires 16m cable length, which also is the standard configuration, see
also System connections in chapter 5.
Wallstand loading and position should be carefully planned since it will have large impact on
the final layout of the room. If the use of armrest is restricted to one side it is also possible to
move Wallstand closer to wall.
If recommended dimensions are overridden, necessary notifications, warnings and instruc-
tions have to be considered. This includes safety distances and trapping zones around motor-
ized movements according to IEC 60601-1 3rd edition.
•
(*1x) and (*1y) is chosen considering a limited stroke of the table top (X +/- 400 y +/
-150) and a 500mm clearance to wall and cabinet. If cabinet is placed somewhere
else (*1y) is minimum 1100mm. If lateral projection should be performed see (*3) for
minimum requirements. Smaller rooms require further table top stroke limitations
(max table top movement range X +/-5 00mm, Y +/-150).
•
(*2) is chosen due to the room size in layout 1 ( Figure 5-3 ) and centers the focal spot
coverage area in X-direction related to the room and Table. (*2) must not be less
than 100 mm.
•
(*3) is chosen considering a lateral projection from the back side of the Table. Lateral
projection requires that the table top is moved to its outer position (towards the front
of the Table)
•
(*4) is chosen to give the traverse cable outlet enough clearance to the wall.
•
(*5) is chosen to give the operator enough space to work freely with the Ceiling sus-
pended unit and the Wallstand (see also (*6) ). It is allowed to mount armrest on both
sides when those minimum and maximum dimensions are withheld. Both left-hand
load detector holder (LL) and right-hand load detector holder (RL) are described with
minimum and maximum dimensions.
•
(*5) is also chosen to give the operator enough space to work freely with the bucky/
detector holder since the chosen configuration is loaded from the left side. The
traverse cable outlet (*7) shall, if possible, always be placed as suggested in Fig. 5-
2, since the cable conduits will be in the way of the operator in a projection against
the Wallstand. If the recommended placing of the traverse cable outlet is not possi-
ble, the projection against the Wallstand requires that the tube is rotated to position
D. (consider heel effect)
•
(*6) is chosen to enable a SID of 1800mm (2000mm SID requires that the table top
is moved towards the back of the Table). Ceiling stand have to be in position A to be
able to project in the center of the tilted detector holder.
•
(*8) is chosen to be able to align the tube and the Wallstand. Maximum and minimum
dimensions are stated on the drawing. See also (*5).
•
(*9) must not be less than 250 mm due to the cable outlet of the Wallstand.
