Abstract

A method and device for transforming a Doppler velocity dataset into a velocity vector field, the including: (a) providing a 2D or 3D Doppler velocity dataset, acquired by means of 2D or 3D ultrasonography from an object; b) calculating a velocity vector field by assuming the velocity at each point of the dataset to be the sum of the provided Doppler velocity and an additional vector field derived from an irrotational flow velocity, and by assuming the velocity vector field to be mathematically continuous, therefore solving an elliptical equation of the Poisson type.
