Plaques' in vivo detection, ... -
Deviations of the SLM produced Lattice Structures and Their Influence on Mechanical properties
Vrána, Radek; Koutecký, Tomáš; Červinek, Ondřej; Zikmund, Tomáš; Pantělejev, Libor; Kaiser, Jozef; Koutný, Daniel (MDPI, 2022-04-26)Selective laser melting (SLM) is an additive manufacturing technology suitable for producing cellular lattice structures using fine metal powder and a laser beam. However, the shape and dimensional deviations occur on the ... -
DUCT: Double Resin Casting followed by Micro-Computed Tomography for 3D Liver Analysis
Hankeová, Simona; Šalplachta, Jakub; Van Hul, Noemi; Kavková, Michaela; Iqbal, Afsan; Zikmund, Tomáš; Kaiser, Jozef; Andersson, Emma Rachel (MYJoVE Corporation, 2021-09-28)The liver is the biggest internal organ in humans and mice, and high auto-fluorescence presents a significant challenge for assessing the three-dimensional (3D) architecture of the organ at the whole-organ level. Liver ... -
Fatigue behaviour of titanium scaffolds with hierarchical porosity produced by material extrusion additive manufacturing
Slámečka, Karel; Kashimbetova, Adelia; Pokluda, Jaroslav; Zikmund, Tomáš; Kaiser, Jozef; Montufar Jimenez, Edgar Benjamin; Čelko, Ladislav (Elsevier, 2023-01-26)Metallic porous structures (scaffolds) produced by additive manufacturing represent an important class of personalised implants used in load-bearing orthopaedic applications. As such, their fatigue performance must be ... -
Lumbar Interbody Fusion Conducted on a Porcine Model with a Bioresorbable Ceramic/Biopolymer Hybrid Implant Enriched with Hyperstable Fibroblast Growth Factor 2
