A method for performing motion compensation in a series of magnetic resonance (MR) images includes acquiring a set of MR image frames spanning different points along an MR recovery curve. A motion-free synthetic image is generated for each of the acquired MR image frames using prior knowledge pertaining to an MR recovery curve. Each of the acquired MR images is registered to its corresponding generated synthetic images. Motion within each of the acquired MR image is corrected based on its corresponding generated synthetic image that has been registered thereto.

In a method of a magnetic resonance system and a method and computer-readable storage medium for the operation thereof to acquire magnetic resonance image data of an examination subject, wherein magnetic resonance system has a number of subsystems and a control device, a number of adjustment measurements to adjust at least one subsystem for making a medical diagnostic data acquisition are implemented through the control device. In these adjustment measurements, an adjustment volume associated with the appertaining adjustment measurement is taken into account that encompasses at least one region of a body containing the examination subject. For this purpose, markings established by the control device within image data of the examination subject and characterizing the spatial occupation (position and orientation) and/or a dimension of the examination subject are determined. Based on these markings the spatial occupation and extent of an adjustment volume for an adjustment measurement are determined automatically by the control device.

A system automatically dynamically compensates for inhomogeneity in an MR imaging device magnetic field. An MR imaging compensation system applies swept frequency magnetic field variation in determining an estimate of proton spin frequency at multiple individual locations associated with individual image elements in an anatomical volume of interest and substantially independently of tissue associated relaxation time. For the multiple individual locations, the system determines an offset frequency comprising a difference between a determined estimate of proton spin frequency associated with an individual image element location and a nominal proton spin frequency. The system derives data representing an electrical signal to be applied to magnetic field generation coils to substantially compensate for determined offset frequencies at the multiple individual locations. An MR magnetic field coil generates a magnetic field in response to applying the electrical signal to substantially compensate for magnetic field variation represented by the determined offset frequencies at the multiple individual locations.

An MR magnetic field inhomogeneity compensation system acquires multiple MR data sets representing luminance intensity values of individual image elements comprising corresponding multiple different image versions of at least a portion of a first imaging slice of patient anatomy including fat and water components. The compensation system employs the multiple MR data sets in solving corresponding multiple simultaneous nonlinear equations to calculate local frequency offset associated with magnetic field inhomogeneity at the individual image element location, for an individual image element of the image elements. The local frequency offset comprises a difference between proton spin frequency at the location and a nominal proton spin frequency. The compensation system derives data representing an electrical signal to be applied to magnetic field generation coils to substantially compensate for determined offset frequencies at the plurality of individual locations. A magnetic field generation coil generates a magnetic field in response to applying the electrical signal to substantially compensate for the magnetic field inhomogeneity at the individual image element location.

A system automatically concurrently performs an MR image study acquisition and supplementary image data acquisition. The system includes a detector for providing a signal indicating individual portions of an imaging scan using a first imaging method have ceased. An image data processor automatically concurrently interleaves imaging of a first anatomical portion using the first imaging method and supplementary imaging of a second anatomical portion using a different second imaging method, in response to the signal. The image data processor incorporates identifier data in data representing images acquired using the second imaging method identifying images acquired using the second imaging method differently from images acquired using the first imaging method.
