Matlab pipeline for analysis of PV and BD systems
-
input: binary masks for each system, binary masks of main branches
-
output: numerical results of evaluated parameters
-
pipeline is based on skeletonization, followed by graph conversion and subsequent analysis

The supplementary algorithm to DUCT pipeline was designed to specifically analyze morphological parameters of the BD and PV systems, and is compatible with the 3D binary masks. Using DUCT two separate masks for both BD and PV systems were generated and the analysis was divided in two independent parts. First, the analysis of the entire portal vein and biliary system and second, analysis of the corresponding main branch (= the longest branch) of each system. For detailed analysis and comparison of whole system versus only the main branch, two algorithms were developed. They differ in the input data and the evaluated parameters. For both algorithms, the first step is to create a 3D skeleton of the input binary mask. Example script Liver_analysis_main.m is included to present general use of the pipeline. Any comments, corrections or suggestions are highly welcome.
