Laboratory of 3D Imaging and Analytical Methods

.

Our laboratory focuses on the analysis of shape of biological objects in the context of morphometry, biology and medicine. Our research is applicable in anthropology, orthodontics, plastic surgery and many other fields. To that end, the laboratory is equipped with surface scanners and software.

Morphological comparison of organisms, studies of variability of size and shape, norms and pathologies are hot topics in many biological and medicinal areas. Mere descriptive analysis no longer suffices and is quickly replaced by quantified results. Classic morphometry (biometry) is currently supplemented and in many studies surpassed by geometric morphometry. The use of modern imaging methods for the creation of 3D models allows for the building of virtual databases of structural and developmental defects, unique fossils, comparative sets or pathologies and their storage without degradation on computer media. Moreover, their use for further analyses is also possible.

The analysis of 3D models can be carried out using methods of both classic and geometric morphometry. The novel methodological approach allows for a detailed study of growth and development of skull, its shape- and size-related changes in temporal and geographical context, the tracking of skeletal deviations or intracranial relations in patients with craniofacial malformations, the reconstruction of facial soft tissues and a plethora of other topics. The study of morphology has many uses, for instance the objective evaluation of facial malformation treatment effects, the dependence of function on shape, such as speech defects in patients with cleft lip based on palatal shape. In addition to the above, there is tremendous use of our equipment in forensic anthropology and sociocultural anthropology, for instance in the studies of attractiveness and facial mimics, behavioral signs…

The tools of 3D imaging and analytical methods, including geometric morphometry are most often used in paleoanthropology and bioarchaeology. They contribute to the solutions in topics of macroevolutionary and microevolutionary changes, diachronic trends, biomechanics or to the evaluation of pathological changes in fossil or historical skeletal material.

In our laboratory, we handle both biomedicinal and forensic topics. We also focus on diachronic changes of selected skull sets from upper Paleolithic through early middle ages to recent identified collections or RTG images of current population. The studied phenomena also include stress effects (Harris lines, asymmetry, some pathological processes) on identified collections of postcranial skeletons. These and other indicators of stress have been used in a complex estimation of economic and social relations in a given population and historical period.
