ROI Tool

The term Region of Interest (ROI) is used throughout the tutorial as a synonym for a "Mask", "Binary Mask", "Segmentation" or "Volume of Interest". Technically, it is a binary 3D volumetric image matrix, which is quite similar to 3D image apart from the fact that voxel values are binary (on or off). Thus, a ROI has also the same properties as image (like resolution and matrix size). ROIs are close to what is represented by DICOM SEG objects.

To open the ROItool just go through the toolbox menu of ther vertical iconbar or use the shortcut:
