摘要：
An Echo PIV analysis process, apparatus and algorithm are developed to reduce noise and analyze DICOM images representing a fluid flow of a plurality of particles. A plurality of DICOM images representing sequential image pairs of a plurality of particles is received. The plurality of DICOM sequential image pairs are grouped. The sequential image pairs are correlated to create N cross correlation maps. An average cross-correlation transformation is applied to each cross correlation map to create an image pair vector map for each image pair. A maximizing operation is applied to one or more of the N adjacent image pair vector maps to create a modified image pair vector map for the one or more of the N image pairs. The maps are combined to create a corresponding temporary vector map that are averaged to obtain a mean velocity vector field of the sequential image pairs.
