Digital Subtraction Angiography (DSA)

Scroll Prev Top Next


The Digital Subtraction Angiography (DSA) technique can be applied to a fluoroscopy series (XA) to allow you to visualize blood vessels better. The pre-contrast image (so-called mask) is subtracted from the subsequent images in which the arteries/veins are filled with the contrast media and, thus, the bony or dense soft-tissue areas are removed from the final image.


Enabling DSA mode


1) Open the fluoroscopy series in the viewer.




2) Click on the  subtraction  button Radiant-Dicom-Viewer-DSA-Subtraction-Button on the toolbar or use the  /  shortcut to activate the DSA mode.




3) A vertical toolbar displaying additional DSA tools will appear next to the series preview pane.
