Vector Interpolation Method in Three-dimensional Reconstruction of Tissue Doppler Echocardiography.
A new method of vector interpolation in three-dimensional reconstruction of tissue Doppler echocardiography is developed and applied to the clinical research. Both the amplitude and direction information of functional parameters, such as velocity or acceleration, in tissue Doppler images is utilized to reconstruct dynamic three-dimensional vector field of myocardial tissue motion. The reconstructed three-dimensional field tissue motion can be visualized simultaneously with the three-dimensional anatomical structure to express the correlation between them. Clinical human experiments show that reconstructed results are consistent with the physiological characteristics of the heart. This method may have potential application in the study of cardiac electrophysiology.
