Remote sensing of body and inner organ motion by ultra-wideband radar is a promising alternative to electrocardiogram (ECG) based gating of several diagnostic imaging and image guided therapy modalities, e.g. cardiac magnetic resonance imaging (MRI) and high energy particle therapy. In this paper, we present a noncontact approach for the detection of cardiac mechanics by means of multi-channel UWB...
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...
The specific advantages of ultra-wideband radar make it a technique especially attractive for biomedical applications. The authors partly review the activities in utilizing this novel technique for the benefit of high and ultra-high field magnetic resonance imaging. Topics like motion tracking, MR safety, and navigation for cardiac MRI are addressed.
