Abstract :
The response of the rigid shelled contrast agent biSphere® has been previously studied optically and acoustically over a range of mechanical index (MI). Free bubble models have been used to model the behaviour of rigid shelled microbubbles (MBs). In this work a new theoretical model is proposed and is compared with available ones in terms of agreement with experimental acoustic responses from single MBs.
