A doppler-based regularization problem for intraventricular vector flow mapping

摘要

Recent studies suggest that the analysis of the intracardiac blood flow dynamics via vector imaging can provide relevant evaluation of cardiac dysfunction. In particular, the clinical importance of intraventricular vortex formation has been underlined. Cardiac magnetic resonance and contrast-enhanced ultrasound are commonly used. These approaches, however, cannot be integrated into routine clinical practice. For the purpose of offering robust and clinically-compatible intraventricular vector flow mapping (iVFM), we generalized the Doppler-based algorithm proposed in [10.1109/TMI.2010.2049656] by using a regularized least-squares method with automatic selection of the regularizing parameters.
