Abstract
A method for acquiring (1) experimental measures with interferences of a physical phenomenon, and for reconstructing (2) a point-by-point signal (3) representative of the phenomenon according to at least one dimension that can vary during the experimental measure acquisition, using at least one simulation model (4) of at least one acquisition chain of the experimental measures including at least one interference, and at least one model (8) of each interference in each acquisition chain, each interference model being determined at least from the measures themselves, wherein the simulation and interference models include adjustable parameters (6, 10) depending on experimental conditions, wherein at least one adjustable parameter of one of the models is coupled to at least one adjustable parameter of the other model, and in that the adjustable parameters are optimized in a coupled manner. A device for MRI imaging, NMR, or medical imaging using such a method is described.
