Cardiovascular Magnetic Resonance Myocardial Feature Tracking
Abstract—Heart failure–induced cardiovascular morbidity and mortality constitute a major health problem worldwide and result from diverse pathogeneses, including coronary artery disease, nonischemic cardiomyopathies, and arrhythmias. Assessment of cardiovascular performance is important for early diagnosis and accurate management of patients at risk of heart failure. During the past decade, car...
متن کاملFeature Tracking in Cardiac Magnetic Resonance Imaging
Purpose: An accurate and practical method to measure parameters like strain in myocardial tissue is of great clinical value, since it has been shown that strain is a more sensitive and earlier marker for contractile dysfunction than ejection fraction (EF). Current CMR technologies for strain assessment are time consuming and difficult to implement in daily clinical practice. Feature tracking is...
متن کاملPlasma flow versus magnetic feature-tracking speeds in the Sun
We simulate the magnetic feature-tracking (MFT) speed using axisymmetric advective– diffusive transport models in both one and two dimensions. By depositing magnetic bipolar regions at different latitudes at the Sun’s surface and following their evolution for a prescribed meridional circulation and magnetic diffusivity profiles, we derive the MFT speed as a function of latitude. We find that in...

متن کاملContext-aware Deep Feature Compression for High-speed Visual Tracking
We propose a new context-aware correlation filter based tracking framework to achieve both high computational speed and state-of-the-art performance among real-time trackers. The major contribution to the high computational speed lies in the proposed deep feature compression that is achieved by a context-aware scheme utilizing multiple expert auto-encoders; a context in our framework refers to ...
