The authors in their work wish to prove that technological advancement of modern thermovision technique opens for forensic medicine, as an applied science, new diagnostic possibilities, especially in the scope of the post-mortem examinations. In the past, some attempts were already undertaken to apply thermovision techniques in forensic medicine, those tests, however, were not put in the everyday medical-legal practice. Most of the factors which have an influence in decreasing the value of thermograph tests are not present while biological material is tested post-mortem, therefore, paradoxically, natural elimination of obstacles occurs in such cases, which allows for medical-legal post-mortem diagnostics based on thermograph images. In particular, the most promising is active dynamic thermography which is based on the analysis of thermograms' sequence registered during transitional thermal processes in the examined object (heating or cooling of the object), which is stimulated by an external heat source, and the object's response to this stimulation is a change of the temperature which function in time determines its internal structure. Pathological and injury changes and their results in the form of structural damages of tissues lead to thermal conductivity and capacity which can be noticeable in a thermovision test. There are, then, no theoretical obstacles to the use of active dynamic thermography in post-mortem tests of tissues to evaluate their structure. With today's technological progress, it should be expected that in the near future sensitivity of thermovision appliances will significantly influence the increase of the specificity of obtained images. It can not be excluded that thermography methods could become a back-up method or even an alternative for other imagining methods.
作者在其著作中希望证明，现代热成像技术的技术进步为法医学这一应用科学开启了新的诊断可能性，尤其是在尸体解剖检查范围内。过去，已经有人尝试将热成像技术应用于法医学，但这些测试并未应用于日常的法医学实践中。在对生物材料进行尸检时，大多数会降低热成像测试价值的因素并不存在，因此，矛盾的是，在这种情况下自然消除了障碍，这使得基于热成像图像的法医学尸检诊断成为可能。特别值得一提的是主动动态热成像，它基于对在受检对象（物体加热或冷却）的过渡热过程中记录的热成像序列的分析，该过程由外部热源刺激，物体对这种刺激的反应是温度变化，温度随时间的函数决定其内部结构。病理和损伤变化及其导致的组织结构损伤会导致热导率和热容量发生变化，这在热成像测试中可能会显现出来。因此，在对组织进行尸检以评估其结构时，使用主动动态热成像没有理论障碍。随着当今技术的进步，可以预期在不久的将来，热成像设备的灵敏度将显著提高所获得图像的特异性。不能排除热成像方法可能成为其他成像方法的备用方法甚至替代方法。
