Investigator: M. Majerová   Aluminate glasses are interesting in terms of their basic structure. The main net forming element is aluminum, while in conventional glasses it is e.g. silicon. Aluminate glasses have excellent mechanical properties, excellent corrosion resistance, show better light and heat resistance and better light conductivity than common silicate glasses. Another important property…

Investigator: L. Valkovič Failing heart is like a pump without fuel; where besides depletion in energy rich metabolites tissue often undergoes acidification. Measurement of intra-myocardial pH using typical magnetic resonance methods hindered by the dominant signal originating in blood that obscures inorganic phosphate (Pi) signal. We have therefore developed a new method using long repetition…

Investigators: ŠVEHLÍKOVÁ, J. – ZELINKA, J. – DOGRUSOZ, Y. S. – GOOD, W. -TYŠLER, M. – BEAR, L. Within the cooperation in the Consortium for ECG imaging (www.ecg-imaging.org) we participated in the study about the influence of ECG signal preprocessing methods on the results of the inverse solutions. Data were provided by IHU-LYRIC, Bordeaux. ECG…

Investigators: E. Schulz, A. Stankewitz, V. Witkovsky, A.M. Winkler, I. Tracey One of the main objectives in pain research is to seek and clarify mechanisms to alleviate suffering. In cooperation with our partners, an experiment aimed at investigating the effectiveness of cognitive strategies for the attenuation of pain was conducted. Using the 7T fMRI, the…

Investigators: Švehlíková, E. Cocherová, J. Zelinka, M. Haška, M. Tyšler The activation of heart ventricles during right ventricular pacing was simulated in realistic patient heart geometry using activation models based on cellular automaton (CA) and reaction-diffusion equations (RD). Using the RD model, also normal ventricular activation was simulated that visually matched with the published experimental…

Investigator: M. Hain High-resolution X-ray microtomography methods have helped evolutionary biology (a team led by Prof. Klembara) to solve the problem existing over a century, related to the origin of amniotes and thus an essential stage in vertebrate evolution. This stage of evolution is important because the tetrapods broke their ties with the aquatic environment…

Investigators: J. Švehlíková, M. Teplan, M. Tyšler In the simulation study, we solved the inverse task of ECG electrocardiography in order to evaluate the possibility of localization of premature ventricular activity (PCA) simulated at 8 different points in a realistic model of the ventricles. We used simulated data provided by the Institute of Biomedical Engineering…

Investigator: M. Hain A total of 32 countries are involved in the European COST project “Multi-modal imaging of forensic science evidence – tools for forensic science”. The aim of the project is to support the emergence of innovative, multi-informative and practically usable multimodal imaging methods for the analysis of forensic (forensic) evidence. Imaging technologies include…

Investigator: M. Hain The X-ray microtomographic method of 3D imaging of biological objects was used in an extensive study focused on the comparative anatomy of legless lizards (Anguine Lizards) with emphasis on the species Pseudopus Apodus. Methods of data filtering, rendering and image segmentation were developed within the optimized microCT imaging. The comparison showed significant…

Investigators: I. Frollo, P. Andris, A. Krafčík, D. Gogola, T. Dermek Magnetic resonance imaging requires a source of magnetic field of the highest homogeneity for the entire volume of the object under study. The aim of this result is the presentation of shim coil design methods, theoretical calculations and homogeneous tomograph homogeneity adjustment, based on…
