To understand how myocardial mechanic is rendered by reflected and post-processed ultra-wideband radar signals, we have executed the simultaneous acquisition of radar signals with a high-resolution electrocardiogram. The ultra-wideband illumination was done from several radiographic standard positions to monitor selected superficial myocardial areas during the cyclic physiological myocardial deformation...
To investigate the sensitivity of the reflection coefficient of the human thorax to the displacement of the individual intrathoracic layers we implemented an analytical model. This analytical model closely approximates the stratified arrangement of the thorax and accounts for the dispersive behaviour of the dielectric properties of the different biological tissues in a broad frequency range by utilizing...
To validate physiological signatures acquired by ultra-wideband (UWB)-radar, like breathing and cardiac deformation, we propose the comparison with simultaneously acquired in-vivo magnetic resonance imaging (MRI). In this way it can be evaluated how physiological signals from the thoracic wall and internal structures, e.g., the heart, monitored by UWB-radar correlate with the physiological reality...
