Computational modeling of thoracic and abdominal anatomy using spatial relationships for image segmentation
2004
Real-time imaging
Preserved Fulltext
This paper presents an original hierarchical segmentation approach of several thoracic and abdominal structures in CT and emission PET images. ...
Therefore, structures involved in the segmentation system must be visible in both CT and emission PET images in order to compute a spatial transformation between them. ...
