The Experimental Setup

The methods of this work involved the measurement of temperature and synchronous ultrasonic imaging of tissue in a water bath. The tissue was usually a piece of turkey purchased from a local grocery store or a piece of preserved rabbit liver. The tissue was placed in experimental housing as seen in Figure 1. This housing was then placed in a water bath in an insulated container, as seen in Figure 2.

Also seen in Figure 2 are thermocouples inserted into the tissue. A clearer view of the thermocouples can be seen in Figure 3. These thermocouple attached to a DATAQ device, seen in Figure 4. This device is used to acquire temperature data from multiple (up to 8) channels via thermocouple.

A second device used in the experiment is the ThermoHaake (the device with the screen as seen in Figure 5). This device has 3 purposes: 1) Heat the water bath, 2) Circulate the water bath, and 3) Measure the temperature of the water bath. The water bath is heated by heating coils on the underside of the ThermoHaake. This heating system is used to bring the water temperature from

This system measures the temperature in the tissue from 4 different channels and at the same time measures temperature from two points in the water bath.
