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.
