An Enhanced Approach for Segmentation of Liver from Computed Tomography Images
287-293An accurate segmentation of liver from Computed Tomography (CT) scans is essential for liver tumor research as it
offers valuable information for clinical diagnosis and treatment. However, it is challenging to achieve an accurate
segmentation of the liver because of the blurred edges, low contrast and similar intensity of the organs in the CT scan. In this
paper, an automated model which will segment the liver from CT images using a hybrid algorithm has been used. The
segmentation of liver from CT scan is done with the help of Particle Swarm Optimization (PSO) followed by level set
algorithm. The ultimate aim of using this hybrid algorithm is to improve the accuracy of liver segmentation. Computer aided
classification of liver CT into healthy and tumorous images aids in diagnosis of liver diseases. It can help a great deal in
diagnosis of liver disorders. In order to achieve better classification results, it is of high importance to segment the liver
accurately without an error of over or under segmentation. The results obtained indicate that the approach used in this work
is faster and has 98.62% accuracy, 99.2% specificity, 97.1% sensitivity, 97.8% F-measure, 96.6% Matthews Coefficient
Constant (MCC), 99.08% precision, 97.8% dice coefficient and 95.7% jaccard coefficient in segmenting the liver
