Xradia Versa 520 x-ray computer microtomograph of the German company Carl Zeiss was purchased with funds received within the Russian Government megagrant. The cost of the equipment is 100 000 000 rubles.
The microtomograph is installed at the DSTU laboratory of biocompatible materials mechanics and set up by specialists of Carl Zeiss Russian representative office. The equipment makes it possible to study both external and internal structure of the study object with an accuracy of 1 micron (0.001 mm) by means of non-destructive method.
The device takes flat images of an object with the diameter up to 260 mm and a height up to 300 mm at different angles. Using the obtained data the program builds a 3D model of the object with a spatial resolution up to 700 nanometers.
– The tomograph will help to solve a wide range of problems faced by DSTU researchers. Within the grant we compare the mechanical characteristics of different biological tissues and their density. The equipment is able to enlighten materials with a resolution up to a micron, it is 100 times thinner than a human hair. So we can see the mechanical characteristics of the sample in volume, that will enable us to estimate their changes after intervention or due to various diseases, – said Boris Mitrin, senior researcher at the DSTU laboratory of biocompatible materials mechanics.
Currently, the laboratory staff headed by Professor Michael Swain from University of Sydney are developing methods for creating biocompatible materials for eye and dental prosthetics. Scientists are conducting a comprehensive study of the materials and tissues mechanical beh * avior: affecting by chemistry, volume structure and liquid saturation. The results of the research can be used in restorative ophthalmic surgery and in restorative dentistry.
