Title: Development of a Biomechanical Model for Hydrocephalus
Advisers: Professor Joshua Smith (Dept. of Mechanical Engineering)
A mathematical model is proposed for acute hydrocephalus, a disease in which the flow of cerebrospinal fluid (CSF) is impeded by an obstruction of the Sylvius aqueduct, leading to extreme expansion of the ventricles and damage to brain tissue. A three-dimensional representation of a human brain was created from magnetic resonance imagery. The brain is modeled as a biphasic medium consisting of solid (the cells) and fluid (the CSF) phases. Simulations will determine the ventricular fluid pressure necessary to cause the ventricle dilation associated with hydrocephalus. Results will show the regions of the brain that experience the largest stress, which may be used to predict tissue damage.
