Hemodynamics plays very important roles on development and growth of intracranial aneurysms, abdominal aortic aneurysms and carotid stenoses. This paper presents PIV results obtained for in vitro flow behaviors in a cerebral aneurysm. The approach is based on flow models of complex geometry reproduced by rapid prototyping technique, and refractive index matching between fluid and model. The index matching method, currently based on the silicon material and the aqueous solution of glycerol, permits full optical access to the entire flow domain, suitable for PIV measurement. As an example of this approach, some results taken from PIV measurement of flow fields in the silicon model of a cerebral aneurysm are presented.
