Figure 2. Graphical user interface of the LungCARE© software showing four small screens (default setting): two axial views, of which one has a set slice thickness of 1 mm (above right) and one represents a thick sliding maximum intensity projection (MIP) of adjustable thickness (above left), a coronal view in which the thickness of the thick sliding MIP can be adjusted (below left) and one view that shows the select volume of interest (VOI, below right). To create a VOI, a nodule is selected with a mouse click. The initial structure of interest is marked by a rectangle. If the observer accepts the positioning of this marker, primary (semi-automatic) volumetry is started.
