  • Publication number: 20100198055
    Abstract: In a method and magnetic resonance system for controlling a contrast agent injector used with a magnetic resonance imaging scanner of the system, a user interface is displayed at the control panel of the scanner, for configuring the operating parameters of the injector connected to the magnetic resonance imaging scanner and for controlling the injector in accordance with the operating parameters configured on said user interface, from the scanner control panel.

  • Publication number: 20100191098
    Abstract: A method tracks contrast agent in a magnetic resonance tomography examination with examination table moving continuously in the Z-direction. In the method, a first magnetic resonance signal in a first magnetic resonance measurement without contrast agent. The first MR signal is acquired along a middle k-space line that runs essentially in the Z-direction. Values of k-space along the middle k-space line of the first MR signal are transformed by means of a Fourier transformation in the Z-direction in order to obtain a first profile of the signal intensity in the Z-direction. After a contrast agent injection, a second MR signal is acquired in a second magnetic resonance measurement. The second MR signal is acquired along the middle k-space line. Values of k-space along the middle k-space line of the second MR signal are transformed by a Fourier transformation only in the Z-direction in order to obtain a second profile of the signal intensity with contrast agent in the Z-direction.

  • Publication number: 20100160766
    Abstract: In a method for flow measurement with a magnetic resonance system and a correspondingly designed magnetic resonance system angiography measurement data of a volume are obtained within a body to be examined, a vessel is determined depending on a user input by means of the angiography measurement data, dimensions and an orientation of the vessel are automatically determined from the angiography measurement data, a slice geometry for the flow measurement is automatically determined depending on the dimensions and the orientation, and the flow measurement is implemented using the slice geometry.

  • Publication number: 20100128952
    Abstract: In a method and magnetic resonance (MR) apparatus for correction of artifacts in time-of-flight (TOF) MR angiography, MR signals are acquired in a target volume with the TOF MR angiography technique to generate multiple MR angiography images, pixels with background signal are identified in the angiography images by separation of these pixels from noise and vessel pixels, a signal profile of the pixels with background signal is determined across the target volume, and the MR signal of a predetermined set of pixels of the target volume is normalized with the signal profile of the pixels with background signal.

  • Publication number: 20100045292
    Abstract: In a magnetic resonance apparatus and method for generation of a magnetic resonance angiogram of a subphrenic vessel structure, a subject containing the subphrenic vessel structure is positioned in an imaging volume of a magnetic resonance apparatus, and MR measurement data are acquired using a radial k-space scanning scheme. An image of the vessel structure is reconstructed from the measurement data. Information about movement of the vessel structure to be examined is determined from the acquired measurement data and a movement correction is implemented in the reconstruction of the image using the extracted information.

  • Publication number: 20060258934
    Abstract: The invention relates to a magnetic resonance method for locating interventional devices, in particular in vivo, in which the interventional device bears a marking which in magnetic resonance images influences the measured signals or generates its own measured signals, where the measured signals are processed by means of a one-dimensional signal processing method in order to suppress noise and artefacts. This may in particular be the maximum entropy method, which can be further expanded by the use of model functions. These model functions are subtracted from the measured signals during the iterative method in order in this way to additionally improve the elimination of artefacts. As an alternative to the use of the maximum entropy method, the use of filters, in particular Wiener filters or bandpass filters, is also possible.
