Abstract
Real-time monitoring of tissue ablation is possible by using a vibrating ablation needle coupling lateral shear waves to the tissue. Ultrasonic imaging may characterize the velocity of these shear waves to reveal Young's modulus of the tissue and, at a discontinuity in Young's modulus, a boundary of the ablated lesion reflecting an underlying increase in stiffness of ablated tissue. This technique may be coupled with quasi-static elastography-based ablation monitoring techniques for improved measurement.
