Manual image rotation
The image rotation caused by swiveling of the floor stand or Artis dTC/dTA top
stand is normally compensated automatically by collimator rotation ("Multi-
space"). The image on the monitor is automatically aligned and always displayed
as if the patient were standing in front of the examiner.
Manual rotation For objects lying obliquely with respect to the image, e.g. arms, the primary col-
limator or the image can also be rotated manually. In this case, automatic collima-
tor rotation is switched off. This way, collimation can be performed parallel to the
object:
Rotating the image clockwise:
u Press the top key and keep it pressed.
The upper LED lights up.
The collimators / the image rotate(s) clockwise.
Rotating the image counterclockwise:
u Press the bottom key and keep it pressed.
The lower LED lights up.
The collimators / the image rotate(s) counterclockwise.
A message indicating this appears on the data display.
Switching back to automatic collimator rotation
To switch manual collimator rotation off again:
u Press both keys simultaneously.
The collimators / the image return(s) to the normal position.
The corresponding LED goes out.
The message on the data display disappears.
The portrait/landscape rotation of FD 30x38 is also reset.
