Návrh a realizace nízkonákladového systému pro spouštění sekvencí magnetické rezonance

Abstract

Cardiovascular magnetic resonance (CMRI) is a set of magnetic resonance imaging (MRI) techniques designed to assess cardiovascular morphology, ventricular function, myocardial perfusion, tissue characterization, flow quantification and coronary artery disease. Since MRI is a non-invasive method and without use ionizing radiation, it is suitable for longitudinal monitoring of treatment effect and follow-up of disease progress. Compared to MRI of other body parts, CMRI faces specific challenges from cardiac and respiratory motion. Therefore, CMRI requires synchronous with cardiac and respiratory activities or breath-holding techniques to overcome motion artifacts. The diploma thesis tests two newly furnished sensors (pneumatic, optical) for monitoring basic human life functions. Both tested sensors are compared with the ECG system, which is considered the gold standard CMRI.
