Typical clinical procedure:
❏
Display of an arterial vessel for localizing vascular stenoses with injection of a
contrast medium to enable the contrast-enhanced display of the vascular fill-
ing (subtraction of the native image (mask) from the contrast-enhanced
image).
❏
Alternative to native image display, subsequent inversion of the displayed im-
age allows you to display a catheter introduced into the vessel path using the
Roadmap function.

Selecting an operating
mode
The operating modes can be selected directly at the control panel of the C-arm
system or in the
Examination task card.
The operating modes can also be selected via the corresponding button on the
optional multifunctional footswitch, if used. The switch from one mode to anoth-
er is confirmed with a confirmation tone. You can then release radiation again
right away.

When an operating mode is selected, the LED of the corresponding key lights up
on the control panel. On the imaging system the operating mode is indicated by
a symbol or text display. The current operating mode is deselected when switch-
ing to another mode.
By repeatedly pressing an operating mode key that is already activated, you can
scroll through the exam sets assigned to the corresponding operating mode.
This is only possible if a patient has already been registered.
