X-ray microtomography methods in 3D imaging

High-resolution X-ray microtomography measurement methods have been used in three-dimensional imaging in materials research, biology and paleontology. In non-destructive imaging and characterization of properties of new materials and technologies of additive production using 3D printing, microtomography was used in cooperation with FCFT STU to investigate the repeatability and reliability of 3D printing in additive production of high-density alumina ceramic objects. The methods enabled non-destructive and accurate evaluation of changes in ceramic objects in the process of additive production after the application of individual technological operations – the formation of cracks, deformations and dimensional changes. The results were published in the prestigious journal Additive manufacturing (Q1, D1) [1]. In cooperation with ElÚ SAV, the longitudinal homogeneity of MgB2 superconductor wires produced by the internal magnesium diffusion process was studied using microtomographic measurement methods. The results were published in the prestigious journal Superconductor Science and Technology (Q1, D1) [2]. In the framework of long-term cooperation with PriF UK, X-ray microtomographic methods were used in the study of paleontological findings from the Late Carboniferous period, specifically in the three-dimensional imaging of the morphological structures of the skull and inner ear of the four-legged reptile Limnoscelis dynatis. The results were published in the prestigious journal Frontiers in Ecology and Evolution (Q1, D1) [3].
