Annotation:

Noise and vibration generated in the open-air and the whole-body MRI devices (open-air E-Scan Esaote Opera and whole-body TMR96) during the scanning process has physiological as well as psychological effects on an investigated person. Analysis of the stress effect is performed depending on the intensity and duration of the exposure. The analyzed factors include changes in blood pressure and heart rate – detected in the sensed photoplethysmographic signal, differences of vascular vessels detected from MR images of the human hand, and increase in the stress factor evaluated from the speech signal recorded in parallel. The applicant is expected to have knowledge in areas of human physiology, methods of biomedical signal measurement and sensing, and numerical methods for signal processing.
