Dreidimensionale Bildprozessierung in der HNO- Onkologie zur pr ä operativen Planung und Evaluierung Three-dimensional Visualization for Preoperative Planning and Evaluation in Head and Neck Surgery

Abstract Three-dimensional Visualization for Preoperative Planning and Evaluation in Head and Neck Surgery & There are a lot of diagnostic possibilities for the preoperative planning in head and neck surgery. So far, no study was perform-ed to evaluate if there is an advantage of three-dimensional vi-sualization compared to conventional computed tomography yet. Additionally, there are no speci fi cations for such a visualiza-tion prior surgery in head and neck surgery. This work describes diff erent possibilities for segmentation and three-dimensional visualization for preoperative planning in head and neck sur-gery and tumor volumetry compared to conventional computed tomography. We describe new techniques and speci fi cations for three-dimensional visualization.
