Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging
Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking
Laser &Photonics Reviews, EarlyView.Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Adaptive Waveform Design for MIMO Radar-Communication Transceiver [PDF]
Sensors, 2018 The system architecture for an adaptive multiple input multiple output (MIMO) radar-communication transceiver is proposed. A waveform design approach for communication data embedding into MIMO radar pulse using M-ary position phase shift keying (MPPSK) waveforms is introduced. A waveform optimization algorithm for the adaptive system is presented.
