Top row, the workflow for converting 16bit data into a connected-component image (CC), and eventually quantified data. The CC image is used for the mask on the original data, and the user intervention step illustrated (Top Center) is the identification of the bottom (base) of the lung, and confirmation of the correct lung segmentation index, allowing progression of the analysis from the bottom (base) of the lung to the top (apex) or all the way up to the sinus cavity. The saved volumetric data can be reviewed in multiple formats including orthographic projection slice views (Bottom Left), 3D orthographic views (Bottom Center), and 3D volume rendering (Bottom Right).
