In this case this material is used for the scaffold and ability of reliable imaging of the complex inner structure is crucial for determination of the mechanical behaviour at microstructural level. Microtomographical data are useful for inspection and proper evaluation of the internal microstructural deformations of complex sample and also for the assessment of spatial strain field using numerical computational technique (e.q. digital volume correlation technique). In this study three types of gellan-gum bioactive-glass scaffold samples with different SiO2 content (70 wt%, 50 wt%, 0 wt%) were scanned using three different types of devices and reconstructed to obtain image data for study of morphological characterisation of the sample and further strain assessment and numerical model development. One of the scanning device is conventional commercially available μCT, second device is Talbot-Lau grating interferometer μCT and third setup is patented (EP2835631) custom build μCT setup called TORATOM. All samples are immersed into water to simulate approximate physiological conditions during the scanning. This presents a challenge with
respect to the scaffold's material with low attenuation of X-rays. Obtained image data are compared between each other and suitability of different scanning procedures is discussed.Pracoviště Ústav teoretické a aplikované mechaniky Kontakt Kulawiecová Kateřina, kulawiecova@itam.cas.cz, Tel.: 225 443 285 Rok sběru 2019 Elektronická adresa http://www.ndt.net/article/ctc2018/papers/ICT2018_paper_id151.pdf
