PET/CT segmentation for Head and neck cancer

Hi,

I would like to know which semi-automatic segmentation tools are available in 3D Slicer and could be used to segment tumours in head and neck cancer patients on PET/CT images.

I am used to ‘Level Tracing’, but I could not find a paper about this method.

Could you please guide me if there is a method used for both image modality, and if there is an article about ‘Level tracing’

Thank you

There are several resources. I haven’t personally tried them with recent Slicer versions but they should be working.
