Method for the determination of source distributions according to their biophysical contrast mechanisms for biomedical imaging

摘要

Process for determining source distributions according to their biophysical contrast mechanisms for biomedical imaging. In biomedical imaging, images are created from the superposition of signals from source distributions with different contrast mechanisms. In the known methods, this has a disadvantageous effect on the quantitative determination of individual material and tissue properties. The new method is used to determine the source distributions specifically separated according to their underlying contrast mechanisms. In order to determine at least one underlying, contrast mechanism-specific source distribution from at least one measurement field distribution, an artificial neural network is first trained on it, and at least two contrast mechanism-specific source distributions from at least one input measurement field distribution The method is suitable for mapping the magnetic susceptibility from magnetic resonance phase images.
