Lung CT image segmentation is a key process in many applications such as lung cancer detection. However, various types of nodule and visual similarity with its surrounding chest region make it challenging to develop lung nodule segmentation algorithm. We followed the instructions from the organizer and divided the 60 CT volumes into 36 and 24 volumes for the training and testing respectively. After registration, they can download a set of chest CT scans and apply their segmentation algorithm for lung and/or lobe segmentation to the scans. An alternative format for the CT data is DICOM (.dcm). In this paper, we propose a semi-automated segmentation method for extracting lung lesions from thoracic PET/CT images by combining low level processing and active contour techniques.

Segment Segmentation. In this paper, to solve the medical image segmentation problem, especially the problem of lung segmentation in CT scan images, we propose LGAN schema which is a general deep learning model for segmentation of lungs from CT images based on a Generative Adversarial Network structure combining the EM distance-based loss function. A popular deep-learning architecture for medical imaging segmentation tasks is the U-net. Reproduced from https://wiki.cancerimagingarchive.net. Hence 2-fold cross validation was not used for this dataset. Collapsed lung may be excluded in some scans.
