Intraventricular vector flow mapping-a Doppler-based regularized problem with automatic model selection.
We propose a regularized least-squares method for reconstructing 2D velocity vector fields within the left ventricular cavity from single-view color Doppler echocardiographic images. Vector flow mapping is formulated as a quadratic optimization problem based on an [Formula: see text]-norm minimization of a cost function composed of a Doppler data-fidelity term and a regularizer. The latter cont...
متن کامل3-D Vector tomography of Doppler-transformed fields by filtered-backprojection
Filtered-backprojection formulae for the tomographic reconstruction of three-dimensional, divergenceless vector fields from their line integrals (Doppler transforms) are obtained, for both the cases of longitudinal and transverse measurement. The longitudinal formula is numerically simulated, and shown to be robust in the presence of noise. If, in the longitudinal case, there are non-zero norma...
متن کاملIntracardiac Vortex Dynamics by High-Frame-Rate Doppler Vortography-In Vivo Comparison With Vector Flow Mapping and 4-D Flow MRI.
Recent studies have suggested that intracardiac vortex flow imaging could be of clinical interest to early diagnose the diastolic heart function. Doppler vortography has been introduced as a simple color Doppler method to detect and quantify intraventricular vortices. This method is able to locate a vortex core based on the recognition of an antisymmetric pattern in the Doppler velocity field. ...

متن کاملDoppler vortography: a color Doppler approach to quantification of intraventricular blood flow vortices.
We propose a new approach to quantification of intracardiac vorticity based on conventional color Doppler images -Doppler vortography. Doppler vortography relies on the centrosymmetric properties of the vortices. Such properties induce particular symmetries in the Doppler flow data that can be exploited to describe the vortices quantitatively. For this purpose, a kernel filter was developed to ...
