Semantic navigation is used to synchronize baseline and follow-up CT examinations. The algorithm detects words from the radiology report and puts links on it to automatically travel to the proper region in the images. To achieve this the software automatically detects landmarks in the anatomy and connects this to semantic information using rekationships like 'close to', 'above', 'to the right of', etcetera. this method allows matching of non-corresponding exams and provides clinically sufficient automatic alignment of corresponding findings in consecutive examinations.
