The temperature in a living human body is maintained at constant value, which is also called homoiotherm. However, these thermoregulatory processes cease after death and consequently the body temperature decays after death. This makes the body temperature a crucial measure in the field of forensic medicine. In forensic routine, the body temperature is used to determine the time of death and enables the detection of hyper- or hypothermia at death. Additionally, it is well known that magnetic resonance imaging (MRI) is temperature sensitive, which is highly relevant for postmortem examinations. Therefore, the determination of the exact temperature of the investigated body site, e.g. the brain, is crucial. However, direct temperature measurements are invasive and inconvenient. Our group aims to investigate non-invasive methods to substitute invasive temperature measurements by examining and comparing temperature profiles of both the body core and skin.
