This paper presents the development of automatic segmentation of the inferior vena cava (IVC) in the proximity of the liver in abdominal CT scans. In our proposed framework, starting from an initial contour mask the active contour method is used to delineate the IVC by propagating an elliptical contour in each image slice sequentially in the CT scans. The framework consists of three main steps: general vessel enhancement and segmentation, initial contour delineation and localized active contour propagation. The framework was tested on the publically available IRCAD data set. The results are promising and show good overlap with the IRCAD IVC ground truth data set.
