DR workflow for DSA roadmapping

This workflow is available only on DR systems that support digital subtraction
angiography roadmapping.
The roadmapping examination is performed as part of a DSA examination.
The result of a roadmapping examination is a roadmapping sequence. Also
DSA sequences, fluo sequences and static images can be acquired in the same
session, before or after the roadmapping examination.
First a roadmapping examination produces the roadmapping mask by
acquiring a fluo sequence during injection of a contrast medium. The
roadmapping mask is displayed as a subtracted image in which the blood
vessels are filled with contrast medium. If the maximum opacity functionality
is enabled, the blood vessels are visualized with maximum opacity.
The last image of this first sequence is used as a mask to subsequent
fluoroscopy exposures during the same roadmapping session. Blood vessels
become clearly visible (as a roadmap), as well as catheters or guide wires that
are moved through the vessels.
To perform a roadmapping examination:
1. Add a DSA group to the Image Overview pane.
If a DSA group has already been added based on data from the RIS, this
step can be skipped.
a) In the Examination window, click Add Image.
The Add Image window appears.
WARNING:
The user has to finish the roadmapping workflow completely
before performing any other actions. This means that e.g.
checking or selecting previous (reference) images should be
done upfront, prior to starting a roadmapping workflow.
Otherwise these actions may cause the roadmapping workflow
to be closed and the whole procedure has to be restarted.
