Paper Abstract
Automatic segmentation of anatomical structure is crucial for computer aided diagnosis and image guided online
treatment. In this paper, we present a novel approach for fully automatic segmentation of all anatomical structures from a
target liver organ in a coherent framework. Firstly, all regional anatomical structures such as vessel, tumor, diaphragm
and liver parenchyma are detected simultaneously using random forest classifiers. They share the same feature set and
classification procedure. Secondly, an efficient region segmentation algorithm is used to obtain the precise shape of these
regional structures. It is based on level set with proposed active set evolution and multiple features handling which
achieves 10 times speedup over existing algorithms. Thirdly, the liver boundary curve is extracted via a graph-based
model. The segmentation results of regional structures are incorporated into the graph as constraints to improve the
robustness and accuracy. Experiment is carried out on an ultrasound image dataset with 942 images captured with liver
motion and deformation from a number of different views. Quantitative results demonstrate the efficiency and
effectiveness of the proposed algorithm.
