Part 1 (of 2); Seattle, WA, USA; ; 7 November 1995 through 10 November 1995 | Volume: | 2 | Conference: | Proceedings of the IEEE Ultrasonics Symposium | Abstract: | The effect of temperature and thermal dose referenced at 43 °C on the attenuation and absorption was studied in dog muscle, liver and kidney in vitro. 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 |
