Summary:A method of generating a quantitative susceptibility mapping (QSM) map capable of reconstructing data having various resolutions using a given network trained at a specific resolution includes preparing a local field map having input resolution resolinput, generating a plurality of sub-images having training resolution resoltrain by resampling the local field map, inputting each of the sub-images into QSMnet_resoltrain, which is an inference network trained with the training resolution, acquiring a plurality of QSM sub-images having the training resolution resoltrain from the inference network, generating one QSM assembled map by assembling the plurality of QSM sub-images, and generating a QSM map (corrected QSM map) from the QSM assembled map by applying a dipole compensation method.
