DR workflow for digital subtraction angiography
(DSA)
This workflow is available only on DR systems that support digital subtraction
angiography (DSA).
The result of a DSA examination is a DSA sequence. Also roadmapping
sequences, fluo sequences and static images can be acquired during a DSA
examination.
The DSA sequence consists of a rapid sequence exposure. Right after the start
of the exposure, a first set of frames is used to generate a mask image. Then a
contrast medium is injected. Subsequent frames from the same exposure are
displayed after subtraction of the mask image. Blood vessels that contain the
contrast medium, become clearly visible without the interference of bones or
dens soft tissue in the environment.
To perform a DSA 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.
b) Specify the exam group and exam type by clicking on the buttons.
c) Select an exam type that is configured as a DSA group and click OK.
The DSA group thumbnail is added to the Image Overview pane.
A DSA group thumbnail is indicated with an icon in the top right corner of
the thumbnail.
