摘要： Systems and methods for producing velocity data associated with three-dimensional (3D) flow field images. In some embodiments, the method includes receiving data associated with a plurality of frames of a flow field relating to image data acquired by a medical imaging device, in which the data includes information corresponding to measurements of the flow field over time within a chamber; performing, for each of the plurality of frames, the following operations including: generating, for a respective frame, a data correction based on an interaction of the flow field with the chamber, applying the data correction to a velocity field corresponding to the respective frame, and imposing an incompressibility constraint for the flow field on one or more data points of the respective frame; and generating, subsequent to imposing the incompressibility constraint, a plurality of corrected velocity fields each of which corresponds to one of the plurality of frames.
