Měření a analýza bioelektrických signálů při vyšetření pacienta zobrazovacími metodami v medicíně

Abstract

This thesis focuses on the recording of biosignals with the use of non-metallic bio-potential electrodes and conductors made of a conducting polymer polyaniline (PANI) or polypyrrole (PPy) and a carrier substrate made of cotton or carbon fiber in a CT and MR imaging environment. The objective of this study is to test the effects of the set of sensors on the acquired images, namely the occurrence of image artefacts, and the effect of the imaging modalities on the recorded ECG signal. The theoretical part describes the parameters of the biosignals, the principles of imaging methods with a more detailed description of CT and MR, it also characterizes the used biopotential electrodes. The practical part describes the construction procedure and testing of created electrodes and conductors, as well as the comparison of the quality of individual electrodes-conductor combinations. In the next part I am testing an ECG record from an artificial patient with imaging of electrodes on phantom in CT, as well as measuring ECG on volunteers in MR with subsequent processing of collected data.
