Ultrasonic measurements of temperature in materials

Manufacturing processes and product development for industrial medical applications are submitted to rigorous quality control. Quality assurance may provide accuracy of the physical quantities concerned guarantee that defects do not arise when is developed. Quantities, such as temperature distribution play a significant role must be monitored prevent material damage. However, number techniques sense inside bulk in non-invasive non-ionizing way rare. Ultrasonic estimation can overcome this issue, providing an alternative technique matches requirements measure heating within materials. Here, we investigate ultrasonic velocity function metals, polymers gel mimic soft tissues (phantom), biological tissues. Through customized computational algorithm, successfully estimated heat source at surface, throughout length material.
