摘要： In a method to determine a background phase in phase values of a phase image data set that is acquired from an examination subject, wherein the background phase is determined in a partial region of the phase image data set, the phase image data set of the examination subject is acquired, and a substantially closed, planar contour is established in the phase image data set around the partial region, the planar contour having a contour area with a width of at least one pixel of the phase image data set. The phase values in the partial region are determined with the assumption that the spatial curve of the background phase is a harmonic or quasi-harmonic function, the phase values of the pixels in the partial region being determined based on the phase values in the planar contour.

摘要： In a magnetic resonance (MR) method and apparatus for spatially resolved determination of at least one MR parameter that influences an MR signal detected in an MR measurement of a region of an examination subject, first complex image data and second complex image data, respectively acquired with different acquisition coils and at different echo times in an echo imaging sequence, are provided to a processor. The different image data sets have complex image points that correspond with each other with regard to the imaged volume element of the examination subject. The MR parameter is determined in the processor for at least a portion of these image points by determination of an image point vector respectively for the first and second echo times and by combining the image point vectors to at least partially compensate echo time-independent phase or magnitude portions in the acquired image data.

摘要： In a method and system for phase-sensitive magnetic resonance imaging, a respective, complex image data set provided to a processor for each of at least two different echo times, the complex image data sets for the different echo times having been reconstructed from magnetic resonance data that acquired for the different echo times using an echo imaging sequence, at least one complex division image data set is determined in the processor by complex division of the complex image data sets for the two different echo times. The two different echo times define an echo time difference, so the resulting complex division image data set has phase components that are dependent on the echo time difference.

摘要： In a method to correct a B0 field drift in a temperature map exposure obtained by magnetic resonance tomography as well as a device to implement such a method, a magnetic resonance phantom is placed at a stored, marked reference position relative to an acquisition coil. A first reference phase image of the phantom is automatically acquired in the acquisition of a first phase image of an examination subject in the unheated state. A second reference phase image of the phantom is automatically acquired in the acquisition of a later second phase image of the examination subject. The phase images are adapted to one another according to the requirements of a calibration of the associated reference phase images.
