ABSTRACT
In this work we investigate the removal of emboli from cardiopulmonary bypass circuits via acoustic radiation force. Unless removed, emboli can be a significant source of cognitive deficit after cardiac surgery. We have implemented both inviscid linear and viscous non-linear models for radiation force on a sphere immersed in a fluid. The importance of viscosity is a lingering question in the literature. These models allow for prediction of radiation force as a function of embolus size and can identify the optimal frequency for clinical use.
