Image restoration method based on learned nonlinear mapping

摘要

The present invention relates to an array processing image reconstruction method, comprising the steps of: receiving (13) a series of echo waveforms from an object of interest as measured values; defining a measurement model by connecting an unknown image of an object to a measurement value (15); defining a data fidelity function using the measurement model (17); defining a normalization function using the learned nonlinear mapping (19), wherein the normalization function includes prior knowledge of the unknown image; defining (21) an optimal solution comprising a data fidelity function and a normalization function to obtain a first image estimate of the unknown image; and solving an optimal solution to obtain a first image estimate (23).
