Abstract
The present invention concerns an array processing image reconstruction method comprising: receiving (13) a set of echo waveforms as measurements from the object of interest; defining (15) a measurement model linking an unknown image of the object to the measurements; defining (17) a data fidelity functional using the measurement model; defining (19) a regularisation functional using a trained non-linear mapping, the regularisation functional comprising prior knowledge about the unknown image; defining (21) an optimisation problem involving the data fidelity functional and the regularisation functional for obtaining a first image estimate of the unknown image; and solving (23) the optimisation problem to obtain the first image estimate.
