Abstract:
Online temperature measurement in biological tissue would improve the hyperthermia therapy. This contribution presents a novel method for measuring the shear wave speed in biological tissue with very small echo signal amplitudes from scattering particles. Since the tissue’s properties change during heating, it is not possible to average measures taken over a long time period to improve Signal-to-Noise-Ratio (SNR). The novel method relies on evaluating the signal’s energy as a function of time shifted signals instead of using a cross correlation. For reproducible experiments, a tissue phantom made of polyacrylamide and algae is used.
