ROI (Region of Interest)
Use ROI to define regions of interest, e.g., a nidus on the angiogram.
How to Use ROI
Scroll through the images using the sliders ① (or mouse wheel) to find regions of interest.
Select ROI Brush.
Highlight a region of interest in one view by drawing an outline ②.
The area is marked in blue and creates a ray ③ in the other view.
Highlight the region of interest in the other view.
If needed, use ROI Erase to define the borders more accurately.
Optionally, select Undo to undo previous brush/erase steps.
Verify the ROI Brush object.
Use the drop down menu to switch between DSA (grayscale) and CIP (color) views to help identify regions of interest more easily.
|CIP||Color Intensity Projection: Dynamic angio flow with color-coded time information based on DSA images.|
|DSA||Digital Subtraction Angiography: Displays the angiography imaging in grayscale.|
