Extracting Pulmonary Artery Area in the Mediastinum from Multi-slice Chest CT Images by Model Matching

Abstract

The method using a medial axis model, which we proposed before, extracted aorta areas from multi-slice chest CT images properly. In principle, a pulmonary artery area can be extracted by the same method. However the modification was needed in the process to determine the initial model location and to restore the shape when the method applied to the extraction of a pulmonary artery. The modified method was applied to 29 patient cases and we confirmed its effectiveness from the results.
