Lustberg, Tim; The challenge provided 120 three-dimensional cardiac images covering the whole heart, including 60 CT and 60 MRI volumes, all acquired in clinical environments with manual delineation. Most of the current semi-automatic segmentation methods rely on human factors therefore it might suffer from lack of accuracy. Lung segmentation. All CT scans covered the entire thoracic region with a 50‐cm field of view and slice spacing of 1, 2.5, or 3 mm. In CT lung cancer screening, many millions of CT scans will have to be analyzed, which is an enormous burden for radiologists.
