Computer assisted planning systems based on patient specific tomography data has been proofed to be useful in several medical fields. Patient's tomography data can be shown in several views and can be enhanced with additional information useful for the planing process. The STAN (Simulation Tool for Airflow in the human Nose) system overlaps patient data and CFD (computer fluid dynamics) data resulting from flow simulations of the airflow in the patient's nose channel. To verify the simulation results experimental investigations, and measurements are made in nasal models. Silicon Models of patient's nose channels are made to analyze flow characteristics. The CT or MR scans of the same patients are used as input data for the simulation. The experimental outcome is compared to the simulation results to validate this diagnostic approach.
