Wallstand loading and positioning 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 the Wallstand closer to wall or Table. If a non-tilt Wallstand is used, there will be more
space to place it, since the foot print is smaller and horizontal projection doesn’t have to be
considered.
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 the cabinet is placed some-
where else, (*1y) is minimum 1100mm. If lateral projection should be performed, see
(*3) for minimum requirements. Smaller rooms require further table top stroke limita-
tions (max table top movement range X +/-500mm, Y +/-150).
•
(*2) is chosen due to the room size in layout 1 ( Fig. 5-1 ) 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. If the
table top is centered over the Table, minimum distance is 1289mm. A minimal dis-
tance of 1189 mm can be chosen, but 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.
•
(*6) is chosen to give the operator enough space to work freely with the bucky/detec-
tor holder since the chosen configuration is loaded from the left side. The traverse
cable outlet (*7) shall, if possible, always be placed at the opposite side of the Wall-
stand to avoid collisions. If the recommended placing of the traverse cable outlet is
not possible, (*6) should not exceed 800 mm.
•
Also consider the traverse cable conduits when placing the traverse cable outlet on
the same side as the Wallstand. The conduits will hang down over the head end of
the Table when choosing this option.
•
(*8) is chosen to enable a SID of up to 2000 mm, and to enable the Ceiling suspend-
ed unit to be aligned with the image receptor, when the Wallstand bucky/detector
holder is tilted.
•
(*9) is chosen to enable exposures in the center of the tilted detector. See also (*8).
The distance, measured from the back of the Wallstand, is variable but must not be
less than 250 mm due to the cable outlet of the Wallstand.
