Preliminary work on Zenker diverticulum segmentation

Zenker´s diverticulum (ZD), also known as pharyngoesophageal diverticulum, is a relatively rare ailment in the pathology of the esophagus, which still accounts for 63% of the diverticula in this digestive segment, affecting men more frequently than women. This study comprises of 35 cases of patients (over the 2001-2014 period) at the Clinic of General and Esophageal Surgery, under the supervision of Prof. Dr. S. Constantinoiu. More precisely, the study deals with the analysis of 35 radiological images that feature the morphological characteristics of the diverticulum. This paper proposes an automatic segmentation of the diverticulum and a morphological evaluation of it based on the Van Overbeeck classification. It also evaluates the segmentation quality by border error metric and the size diverticulum evaluation.
