Changing the zoom stage
u Press the - or + key on the collimator control module.
– The zoom stage is reduced (= larger input field) or enlarged (= smaller input
field) by one step.
Collimation One of the following primary collimator responses to switching the zoom stage
can be configured by Siemens Service:
o The collimation size is retained.
o The collimation size is retained but the collimation is opened to the edge of
the image with Zoom -, if collimation is not performed manually (default).
o The collimator leaves are fully opened.
o Collimation with respect to the monitor is retained.
An automatic control ensures that collimation remains constant if there are any
changes in the distance from the focus of the X-ray source to the image receptor
plane.
Measuring field
(dominant)
If the input field was reduced and a measuring field was selected which would
now be cut, it is automatically switched over (center measuring field).
Changing from Zoom 2 to Zoom 3 (with flat detector 30x38 only) X-ray is inter-
rupted due to mode change. No live image is displayed for a short time.
The size of the active input field is shown on the data display.
