Abstract
A training method for a system with a machine learning model for de-noising images, including: providing numerous image datasets, wherein each image dataset includes a plurality of complex-valued image repetitions; performing a phase correction on the image repetitions, wherein for each provided image repetition of an image dataset a phase-corrected signal image is calculated by amending the phase of the complex-valued image repetition such that the phases of the image repetitions of the image dataset are consistent and such that the signal image comprises signal contribution of the image repetition; calculating a noise map for an image dataset based on the standard deviation between the signal images of this image dataset; and training the machine learning model based on the signal images, the noise map, and a loss function based on Stein's unbiased risk estimator.
