The ultrasonic echo method is a simple and useful way of observing cross sections of extremities. However, due to the narrow view through the probe and its incapability to take images behind bones, combining multiple images is necessary in order to capture cross-sectional images of the whole extremity. Therefore, tissue deformation caused by pressing the probe when taking pictures is a problem. In this study, we investigated the conditions under which high-quality images of extremities can be taken, after avoiding the deformation of tissues by using a water bath together with the ultrasonic echo device. As a result, we found that use of a water bath having similar acoustical impedance to that of biological body and keeping the water at about 40 degrees while shooting enabled to obtain high-quality images.
