Step 3.3: Segment the lesions
Various segmentation tools are available, from basic manual contouring, to thresholding and more advanced automated tools.
For segmenting the lesion in PET, we will use a specialized automated tool presented by Beichel et al in this manuscript.
To segment a PET lesion using this tool, first enable it from the list of segmentation tools, and then click within the primary lesion region in the axial slice.
Try it yourself: Repeat the same sequence of steps to segment the Secondary lesion!
