Vývoj modulu systému FOTOM 2008 Plus pro automatické segmentace nosních dutin na snímcích CT za účelem následného vyhodnocení

Abstract

This diploma thesis deals with development module of the FOTOM 2008 Plus. The FOTOM was created as a photogrammetric system for analyzing and evaluating objects in images. It is used for subsequent evaluation of cavities. The thesis is divided into several parts. In the first part I deal with the problems of the segmentation paranasal sinuses and their anatomical structure. The following section focuses on selecting the appropriate filter in CT images. In addition, module was created using active contours to detect objects in CT images and create an output text file containing information about objects in the images. In the last part there is a proposal of a statistical solution for future research at the department of otorhinolaryngology and head and neck surgery at the University hospital Ostrava. Here the FOTOM 2008 Plus with module is used as a tool for measuring the volume of paranasal sinuses.
