Investigators: Ladislav Valkovič, Pavol Szomolányi Quantifying the concentration of energy metabolites requires accurate measurement of the magnetic field (B1), especially at 7T where the excitation coils face large field inhomogeneities. Measuring the B1 field using standard signal sampling is relatively time-consuming. It takes about 40 minutes to cover the entire heart, which is too long…

Investigator: Radka Klepochová In this work, we focused on obtaining information about two key processes at the same time: the depletion and recovery of intramuscular phosphocreatine (PCr) using ³¹P MRS and the behavior of the creatine CH₂ signal in ¹H MRS, which exhibits similar dynamics. While previous studies required separate ¹H and ³¹P measurements with…

Investigators: Viktor Witkovský (ÚM SAV), Gejza Wimmer (MÚ SAV), Anna Charvátová Campbell (ČMI), Petr Klapetek (ČMI), Radek Šlesinger (ČMI) As part of the international bilateral SK-CZ project, we designed and implemented efficient computational methods for evaluating the mechanical properties of materials at the nanoscale using instrumented indentation (IIT) and atomic force microscopy (AFM). The OEFPIL…

Investigators: Ladislav Valkovič, Iveta Pajanová Cardiac energy metabolism is still rather dependent on the experience of the operator, both at the acquisition and analysis stages. Mainly because any shift in the acquisition matrix or wrong voxel selection increase inaccuracy, which is one of the reasons why this promising technique is not yet used in clinical…

The research focused on the development of a new type of aluminosilicate glass and glass-ceramics. The effect of the method of preparation of gelenite glasses (2CaO-Al2O3-SiO2) doped with Bi was investigated. The glasses in question were prepared by a combination of flame synthesis and solid-phase reaction and a rapid cooling method. The obtained knowledge can…

Investigators: Milan Tyšler, Richard Bagín, Daniel Gogola, Fedor Lehocki, Beáta Ondrušová An innovative system for monitoring the vital functions of injured persons during mass disasters was developed. The system features smart patches designed to record electrocardiograms, photoplethysmograms, respiratory movements, and body temperature from the chest of injured persons. The patches autonomously evaluate heart rate and…

Investigators: Švehlíková J., Ondrušová B., Zelinka J., Tyšler M., Hlivák P., Rasoolzadeh N., Serinagaoglu-Dogrusoz Y.S., The aim of the joint project of the IOM SAS and Middle East University in Ankara was to apply the inverse electrocardiography methods used at each site to the same data from multi-lead chest measurements. We applied the inverse methods…

Investigator: Ladislav Valkovič, Ústav merania, v. v. i., SAV Our non-invasive methods for energy metabolism assessment using phosphorus MR spectrscopy are ideal for treatment testing in patients, where cardaic or skeletal muscle metabolism is impaired. Hence in collaboration with Boeringer Ingelheim, we have tested the potential mecahnism of effect of their new sodium-glucose co-transporter inhibitor…

Investigators: Viktor WITKOVSKÝ, Laura HAJZOKOVÁ , IMS SAS + foreign partners In 2023, our collaboration with researchers from the University of Montenegro contributed to advances in probabilistic modelling and numerical methods and algorithms for the computation of complex probability distributions, which are often encountered in the analysis of uncertainties in measurement results in various application…

In 2022 The department of optoelectronic measurement methods of the ÚM SAS was actively involved in solving the problem of multimodal imaging as part of international cooperation, focusing mainly on the fields of biology, paleontology, cultural heritage, mineralogy, and also on material and forensic science. This year, the SAV Measurement Institute participated in the solution…
