A tubular model based segmentation method for cystic artery and three-dimensional visualization of Calot's triangle / 国际生物医学工程杂志

ABSTRACT

Objective To explore the feasibility of tubular model based segmentation method for cystic artery and three-dimensional (3D) reconstruction model of Calot's triangle.Methods A tubular model based 3D region growing algorithm was proposed for the segmentation of cystic arteries and its adjacent vessels from 13 patients' CT images in DICOM format.The data was transferred to 3D visualization workstation based on a set of CalotShow1.0 software for 3D reconstruction.Results The method could effectively segment cystic artery and obtain the 3D model of Calot's triangle.Conclusions The 3D reconstruction model based on tubular model related vessel segmentation method and CalotShow1.0 can accurately display the spatial positions and adjacent relationships of cystic artery and Calot's triangle.
