It was found that the attenuation and absorption increased for temperatures higher than 50 °C, and eventually reached a maximum at 65 °C. The change in attenuation or absorption when necrosis is produced was to about twice the value at 37 °C. The change in attenuation or absorption occurred at thermal doses of 100-1000 min which corresponds to the range of threshold of necrosis. The maximum attenuation or absorption was reached at thermal dosages in the order of 107 min.||Description:||Proceedings of the IEEE Ultrasonics Symposium, Volume 2||ISSN:||1051-0117||Rights:||© IEEE||Type:||Conference Papers||Affiliation :||Indiana University|
