Methods of Tissue Temperature Measurement

Methods of Tissue Temperature Measurement

In this chapter various techniques for the non-invasive monitoring of tissue temperature are reviewed, including the proposed NIRS method, highlighting their relative advantages and disadvantages. The emphasis is on the new-born human brain, since, as discussed in Section 1.1, one of the major applications of the work developed in this project is the intended monitoring of cerebral temperature during hypothermic treatment in birthasphyxiated infants.

Section 4.1 discusses the definition and measurement of core body temperature by
conventional and other non-invasive methods. It can also be important to measure temperature in a particular part of the body or even a specific volume of tissue. As discussed in Section 1.2.3, one example of this is the case of selective head cooling, in which cerebral temperature may significantly differ from that in the rest of the body. Therefore, Section 4.2 describes methods in which non-invasive temperature measurement can be applied to localised tissue areas, again with particular focus on the infant brain. Finally, Section 4.3 discusses the feasibility of using NIRS to monitor tissue temperature non-invasively, describing how temperature affects the optical properties of tissue and reviewing studies in which the temperature-dependence of NIRS tissue measurements is investigated.
