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.

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.
