Automatic Segmentation

The PET/CT viewer includes a contribution from ESIEE school (Paris - Eloise Grossiord and Laurent Najman) for an full body automatic segmentation algorithm.

To use the automatic segmentation, go to "Nifti" Tab and select the area of the calculation. The calculation time is usually less than one minute. 

The algorithm delineate each focal uptake and is not specific so physiological uptake are also segmented. However it is simple to review the automatic ROI and erase the false positive with a one single click (using the same interface that manual ROI). 

If uptake are missing (usually for low uptake) you can add them drawing manual ROI.
