    • The invention relates to 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 said 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 said experimental measures including at least one interference, and at least one model (8) of each interference in each acquisition chain, each interference model (8) being determined at least from the measures themselves, characterised in that the simulation and interference models include adjustable parameters (6, 10) depending on experimental conditions, wherein at least one adjustable parameter of one of said models is coupled to at least one adjustable parameter of the other model, and in that the adjustable parameters (6, 10) are optimised (2) in a coupled manner. The invention also relates to a device for MRI imaging, NMR, or medical imaging using such a method.
    • 本发明涉及一种用于获取(1)具有物理现象的干扰的实验测量的方法,以及用于根据至少一个维度来重建(2)代表所述现象的逐点信号(3),所述维度可以在 使用至少一个所述实验测量的至少一个采集链的至少一个仿真模型(4)(包括至少一个干扰)以及每个采集链中的每个干扰的至少一个模型(8),每个干扰模型( 8)至少从所述测量本身确定,其特征在于,所述模拟和干涉模型包括取决于实验条件的可调参数(6,10),其中所述模型之一的至少一个可调参数耦合到至少一个可调 参数,并且可调参数(6,10)以耦合的方式优化(2)。 本发明还涉及用于MRI成像,NMR或使用这种方法的医学成像的装置。
