Synopsis

Keywords: Hybrid & Novel Systems Technology, Image ReconstructionNon-contact synchronization MRI with heart motion is still an open challenge. Inaccurate cardiac gating often complicates image reconstruction and leads to poor or non-diagnostic images. Continuous wave doppler radar is a non-contact, noninvasive novel systems technology that could monitor cardiac motions without distortion from the MRI electromagnetic environment while offering an alternative to state-of-the-art (ECG) triggering.
