Cardiac motion tracking using CINE harmonic phase (HARP) magnetic resonance imaging.
This article introduces a new image processing technique for rapid analysis of tagged cardiac magnetic resonance image sequences. The method uses isolated spectral peaks in SPAMM-tagged magnetic resonance images, which contain information about cardiac motion. The inverse Fourier transform of a spectral peak is a complex image whose calculated angle is called a harmonic phase (HARP) image. It i...
متن کاملHarmonic Phase Flow for Tissue Motion Estimation in Tagged MR Sequences
In this work, we present a fully automated method for tissue deformation estimation in tagged magnetic resonance images (TMRI). The method consists of two main stages: in the first one, we use Gabor filter banks, tuned independently for each left ventricle level, that allows to obtain optimally filtered complex images the phase of which is a property that remains constant along the cardiac cycl...
متن کاملProspective motion correction for intra-cardiac 3D delayed enhancement MRI using an MR-Tracking Tetrahedron
Introduction Myocardial Delayed Enhancement (MDE) MR imaging has been used for visualization of myocardial scar tissue created due to radio-frequency ablation (RFA) of the left atrium for the treatment of atrial fibrillation [1,2]. After administration of gadolinium-DTPA contrast, ECG-gated 3D-MDE is performed with an inversion-recovery preparatory pulse, followed by a segmented k-space gradien...
متن کاملValidation of 3D-HARmonic Phase (3D-HARP) for cardiac motion estimation
L. Pan, J. L. Prince, J. A. Lima, N. F. Osman Johns Hopkins University, Baltimore, MD, United States Introduction MR tagging has been proved to be a prominent technique for noninvasive quantification of regional myocardial function. However the clinical application of MR tagging is still hindered by the lack of fast post-processing techniques, especially 3D reconstruction techniques. 3DHARP has...
متن کاملMR Tag Surface Tracking Using a Spatio -
Magnetic resonance imaging provides the unique capability to produce artiicial, high-contrast features called \tags" that are invaluable for tracking tissue motion. Each tag corresponds to an initially planar surface embedded in the tissue that deforms with tissue motion. By tracking tag surface deformation, quantitative analysis of tissue motion can be performed. In this paper, we present a me...
