5. Evaluation of Region of Interests
You select the image regions to be evaluated by mark-
ing them with ROIs or applying the pixel lens (a circular
ROI with a fixed but configurable diameter). An abso-
lute/relative CT-value calculation is performed for
these selected image.
• You can draw either elliptical or freehand ROIs.
• You can modify an ROI in any image, precisely adapt-
ing it to the shape you feel is relevant.
• The number of ROIs that can be defined is limited to
five – you can only draw one pixel lens.
• The ROIs that you have drawn are transferred to the
other views.
• To aid examination, they are numbered in sequence
and color-coded.
