Roadmap 0
In the first step of the Roadmap examination, the max. fill image is created as a
mask from a normal subtraction (phase A and phase B). You can use the existing
subtraction mask if you have already performed a subtraction angiography during
the current examination. In that case, the first step of the Roadmap examination
is not required.
A previously created subtraction mask can also be used if you have switched to
a different operating mode (such as DR). The subtraction mask symbol (display
to show existing subtraction mask) will remain active.
In the second step, the display of the vessel into which the catheter is to be
positioned is superimposed by current fluoroscopic images (phase C).
Generating a new fill
image
If there is no suitable subtraction mask (e.g. from a previous subtraction angiog-
raphy), you have to generate a new fill image.
