ABSTRACT
This chapter aims to discuss invasive and non-invasive thermometry and imaging techniques necessary for clinical guidance and monitoring of thermal therapeutic apparatus. Thermometry is the oldest and simplest thermal analysis technique. It includes the measurement of temperature as well as time. Clinical thermometry can be performed invasively and non-invasively. Invasive thermometry is the standard for most hyperthermia treatments. A thermocouple is a sensor that measures temperature. It is sensitive to small changes in temperature. Non-invasive measurement of the temperature distribution within the body is an attractive concept with the potential to visualize the 3D temperature distribution during thermal therapy. The advantage of microwave imaging is the ability to see the temperature increase under the surface of human body. Magnetic resonance imaging (MRI) could become the most widely used medical imaging modality if several development variables such as reducing the actual cost of an exam and designing smaller MRI systems come to realization.
