Investigators: V. Juráš, P. Szomolányi, L. Valkovič The goal of the research was to investigate T2 – relaxation parameters mapping as a possible marker for low-grade human articular cartilage lesions during a one-year follow-up, possible changes during the follow-up and compare the reliability and sensitivity of these measurements on high-field (3 T) and ultra-high-field (7…

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…

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: I. Bajla Biologically inspired hierarchical temporal memory (HTM) is one of the successful deep intelligent networks. However, its disadvantage is that it cannot be used directly to solve the detection and recognition of objects in multi-object color images of a complex scene. The basic goal of our research was to find a way to…

(Investigators: A. Cigáň, A. Dvurečenskij, M. Škrátek, M. Majerová, J. Maňka) Polycrystalline samples with a nominal composition of EuBa2Cu3-xSnxO7-δ, where x = 0 to 1.5, were prepared by the solid phase reaction method at 1050 ° C in an oxygen atmosphere. Their structural, superconducting and magnetic characteristics were analyzed based on the results of polarizing…

(Investigators: A. Krakovská, J. Jakubík, M. Chvosteková) In cooperation with the Institute of Informatics of the ASCR in Prague, we focused on the detection of causal relationships between time series. The standard approach is the Granger causality test. In addition, we analyzed methods that estimate conditional mutual information between signals, or work with a degree…

(Investigators: L. Valkovič, I. Frollo) Phosphorus MR spectroscopy (31P-MRS) is a unique technique that allows non-invasive measurement of tissue energy metabolism in vivo. However, due to the low signal-to-noise ratio (SNR), it is still not commonly used in medical practice. MR systems with a magnetic field strength of 7T in combination with surface coils achieve…

(Investigators: V. Juráš, P. Szomolányi, I. Frollo) Although magnetic resonance imaging is currently considered the most accurate method for investigating cartilage damage, morphological imaging is often not sufficient to determine the degree of damage, nor does it detect early stages of degeneration, which are manifested solely by changes in the internal structure of cartilage. Quantitative…

(Investigators: P. Kaľavský, M. Potse, S. Pezzuto, M. Tyšler) A method for computationally fast simulation of electrical activation of an anisotropic model of the heart based on eikonal equations was proposed. The method was implemented in the parallel programming language CUDA and supports massive parallel computations on graphics processors (GPU). The computational speed of the…
