Abstract

A theory is presented and supporting experimental evidence that absolute temperature and small temperature differences may be measured in three-dimensions in suitable materials by an ultrasound computed reconstruction tomographic technique which utilizes the temperature dependence of acoustic refractive index. Such techniques would prove to be of great value in cancer therapy if they could be applied to the measurement of temperature during microwave- or ultrasound-heating induced hyperthermia in tumors. The associated problems and potential for reconstructing temperature in tissues is discussed and examples of reconstructed temperature maps induced by ultrasonic heating in non-living beef muscle is given.
