Bildanalyse Mini-laparoskopischer Sequenzen zur Diagnose von Leberzirrhose

Mini-laparoscopy is a diagnostic technique which is used by clinicians to inspect the organs inside the abdomen. Thin laparoscopes with diameters from 1.9mm – 3.5mm make this technique less invasive compared to common laparoscopy and high definition cameras produce detailed images of organs located inside the abdomen. While a lot of effort has been made in computer assistance of Minimal Invasive Surgery (MIS), no computer assisted diagnostic system for mini-laparoscopy has been developed. For computer aided diagnosis in mini-laparoscopy, reliable features need to be found which are correlated with the target disease. Within the scope of this project, methods for analysis and 3D reconstruction of liver cirrhosis based on mini-laparoscopic sequences are developed. Main focus is given to the precise reconstruction of the cirrhotic liver surface from monocular sequences in presence of specular reflections and illumination change.
