Publication number: 20250225660Abstract: The present disclosure relates to a method of obtaining outlet boundary conditions of blood vessels for computational fluid dynamics simulation of blood flow without in vivo blood pressure measurement. Since it is not required to insert a pressure wire, the method can be applied in situations in which it is difficult to obtain in vivo data through invasive methods such as in the cerebral arteries, so it is possible to obtain outlet boundary conditions for performing arterial blood flow simulation without direct in vivo blood pressure measurement. Further, it is possible to quickly obtain optimal conditions in terms of fluid transport energy loss without performing 3D computational fluid dynamics analysis by using the Windkessel model that is a lumped parameter method.Type: ApplicationFiled: December 31, 2024Publication date: July 10, 2025Inventors: Jae Hyun CHOI, HangJin JO, Jihun KIM
