Abstract

Background: Liver segmentation using computed tomography data is the first step for the diagnosis of liver diseases. Currently, the segmentation of structures and organs is far from the precision level achieved by modern 3D systems based on images performed in the country's hospitals, so it is necessary to search for viable alternatives using the PDI on a computer. Objective: From a computational point of view, to determine an effective variant for the segmentation of liver images for clinical purposes in routine hospital conditions. Methods: Two modern segmentation methods (Graph Cut and EM/MPM) were compared by applying them to liver tomography images. An evaluative and statistical analysis of the results obtained in the segmentation of the images from the Dice, Vinet and Jaccard coefficients was carried out. Results: With the Graph Cut method, the desired region was segmented in all cases, and even when the image quality was low, a high similarity was observed between the segmented image and the reference mask. The level of visual detail is good, and edge reproduction remains true to the reference image. Image segmentation using the EM/MPM method was not always satisfactory. Conclusions: The Graph Cut segmentation method achieved a higher precision for the segmentation of liver images.
