Abstract
Patient specific models are crucial for both simulation and surgical planning. It is not different for the Nuss procedure, which is a minimally invasive surgery for correcting pectus excavatum (PE)—a congenital chest wall deformity. Typically, patients differ not only in size but also severity of the chest depression and type of the deformity, making the simulation process challenging. In this paper, we approach the problem of a patient specific model creation resulting in the development of a parameterized model of the human torso including the ribcage. All the parameters are obtainable from pre-surgical CT. In order to validate our model, we compared the simulated shape of the chest with surface scans obtained from PE patients for both pre- and post-surgery. Results showed that both shapes are in agreement in the area of the deformity, making this method valid for the need of simulating the Nuss procedure.
