Abstract:
The specific heat capacity of tissue is a critical parameter for thermal therapies that act over a long period of time. It is also critical for thermoacoustic signal generation. We present ex vivo measurements of specific heat capacity performed by a dual-pin probe with tight temperature control of the specimen. One 30 mm × 1.28 mm probe heats steadily for 30 s, while another measurement probe measures temperatures 6 mm away from the center of the heater probe. Specific heat values ranging from 2.9 to 4 J cm(-3) °C(-1) were measured on 20 lobes from ten fresh prostate specimens with varying degrees of cancerous involvement as confirmed by histology.

Specific Heat
For example, increasing the temperature of one gram of water by 1°C requires one calorie of heat energy and can be written as 1 cal/g-°C, or 4186 J/kg/K.
