Abstract:
1. A method to generate a series of magnetic resonance exposures of an examination subject, comprising: operating a magnetic resonance data acquisition unit to implement a plurality of first magnetic resonance data acquisitions from a subject while varying a measurement parameter, which strongly influences a contrast of a first material type excited in the subject in the first data acquisitions, from first data acquisition-to-first data acquisition; operating said magnetic resonance data acquisition unit to implement a plurality of second data acquisitions in which a second material type in the subject is selectively imaged that is less contrast-dependent than said first material type with regard to said acquisition parameter; in a processor, calculating spatial correction values for image data of the first data acquisitions, based on spatial differences between image data of different data acquisitions among said second data acquisitions; and in said processor, using said spatial correction values to implement at least one of spatially correcting image data of said first data acquisitions to obtain spatially corrected image data and making the spatially corrected image data available at an output of the processor in electronic form, and bringing image data of different data acquisitions among said plurality of first data acquisitions into registration with each other to obtain registered images and making said registered images available in electronic form at an output of the processor.
