Abstract :
A contact-less, interference-free approach for the detection of cardiac mechanics and respiration by means of multi-channel ultra-wideband (UWB) radar was developed [2], suitable to deliver trigger signals for cardiac MR imaging. Compared to previous systems we increased the number of antennas to four transmitters and eight receiver antennas. This allows measurements of up to 32 channels and makes UWB motion detection less sensitive to the particular positioning of the antennas relative to the heart.
