Modeling HMI Measurement of HIFU Lesion Formation with Temperature-Dependent Tissue Properties

Abstract:

Monitoring tissue stiffness changes during HIFU lesion formation may be possible by measuring the motion induced by the amplitude-modulation of the HIFU beam. As a lesion forms both the stiffness and the acoustic absorption increase. Nominally the increase in tissue stiffness results in less motion, whilst the increase in acoustic absorption results in more forcing and hence more displacement. To investigate whether these two effects cancel out, a finite element model was developed which allo...
