Abstract:
1. A method for transforming a Doppler velocity dataset into a velocity vector field, the method comprising the steps of: a) performing at least one of a 2D and a 3D ultrasound of an object to obtain at least one of a 2D and a 3D Doppler velocity dataset; b) calculating a velocity vector field by assuming a velocity at each point of the at least one of the 2D and the 3D Doppler velocity dataset to be a sum of a provided Doppler velocity from the performing at least one of a 2D and a 3D ultrasound and an additional vector field derived from an irrotational flow velocity obtained by solving an elliptical equation of the Poisson type configured to ensure that the velocity vector field is mathematically continuous; and c) generating and displaying an image of the calculated velocity vector field representing the blood flow in a blood vessel or chamber of a heart.
