Background, Motivation and Objective Three-dimensional intracardiac blood velocities contain valuable clinical information but are currently of limited availability due to the angle-dependency of Doppler methods. This limitation can be overcome using broad transmit beams for high-frame-rate imaging and 3D blood speckle tracking (ST) for estimating 3D angle-independent blood velocities. However, processing time for 3D ST is substantial, and in the pursuit of a real-time modality our aim in this work is to investigate the possibility of using a sparse set of ST measurements, while reconstructing sufficiently accurate and dense 3D vector field based on a fast B-spline interpolation framework.
