2012
Procedia Technology - Elsevier
Preserved Fulltext
Additionally, an algorithm for the lung border extraction in CT images was developed in response to physicians' requirements for a better understanding of each individuals' specific anatomy. ...
This paper presents a novel approach for the fully automatic extraction of the pulmonary boundaries for PET images based in the concept of "marker-driven watershed segmentation". ...
Acknowledgements The authors would like to thank ICNAS for providing the PET and CT exams and to the experts that collaborated in the validation of both algorithms. ...

In this paper, we propose a new method based on an improved graph cut algorithm with context information constraint to find a convenient and robust approach of lung 4D-CT tumor segmentation. ...
The optimization is achieved by solving a max-flow/min-cut problem, which leads to simultaneous and robust segmentation of the tumor in all the lung 4D-CT phases. ...
The rest of our paper is organized as follows: the materials and the details of our method for the tumor segmentation of the lung 4D-CT data will be presented in Section II. ...
