May enable regional LV function assessment from sparse tagged MR in research; leaves open clinical validation and workflow integration.
The proposed estimation theoretic approach enables the reconstruction of dense 3-D left ventricular motion from sparse MR tagged images, allowing for computation of local contractile performance.
Denney et al. (1995) studied Left ventricular motion assessment. Estimation theoretic approach for 3-D displacement field reconstruction was evaluated on Reconstruction of a dense displacement field from sparse displacement measurements. A proposed method based on a multidimensional stochastic model and the Fisher estimation framework successfully estimated a dense displacement field from sparse MR tagged image measurements.
