| MRCartilage – Automatic data evaluation tool from the longitudinal quantitative MRI studies of articular cartilage | |
| Automatický softvérový nástroj na výhodnocovanie kvantitatívnych MRI štúdií artikulárných chrupaviek v čase | |
| Program: | SRDA |
| Duration: | 1.7.2022 – 30.6.2026 |
| Project leader: | Ing. Dr. Szomolányi Pavol, (PhD.) |
| Annotation: | The aim of the project is to design a comprehensive tool for automatic evaluation of human articular cartilage data from quantitative MRI. Data obtained from the Osteoarthritis Initiative database, and measured at Institute of Measurement Science and Medical University of Vienna will be segmented using an automated segmentation tool based on convolutional neural networks. The annotated data will then be registered on quantitative MRI data that will be available from the database (T2 and T1rho mapping, gagCEST, sodium MR) using automated or semiautomated tools developed within this project. The data obtained will be evaluated at multiple time points according to MR measurements that will be available. In addition to quantitative MR data, this will include volumetric data, cartilage thickness, and texture analysis of quantitative maps. Patient evaluation will be based on risk factor groups (transverse ligament rupture, meniscus rupture and menisectomy). The expected number of patients is approximately 4000 divided into individual groups in the ratio 40/30/30. The output of the project will be a compiled version of an automatic cartilage evaluation tool that will be available in a public source (such as website of Institute of Measurement). |
| ETMP – Development and realisation of the standard of the static magnetic field based on a magnetic resonance | |
| Vývoj a realizácia etalónu statického magnetického poľa na báze magnetickej rezonancie | |
| Program: | SRDA |
| Duration: | 1.7.2020 – 30.6.2023 |
| Project leader: | Ing. Andris Peter, PhD. |
| Annotation: | The main aim of the present project is the design of advanced NMR measurement methods using the most advanced range of systems (with a low magnetic field 0.05, 0.2, Tesla) for the development and implementation of standard static magnetic field on a magnetic resonance. This standard would be the basic calibration device fortesting and calibration of the equipments that measure or generate magnetic field.The use of it would be in the Slovak Republic.Orientation research on:- theoretical and experimental research methods for the measurement and mapping of static magnetic fields,- standardizing the measurement metrology protocols,- mapping the intensity of the vibrations generated by the measuring system and modeling of their layouts fordifferent measuring MRI sequences,- spectral analysis of disturbing signals, identification of dominant frequencies and evaluation of their effects on the accuracy and stability of the magnetic standard. |
