The master communication bridge extracts the state of its communication stack and sends it to the further communication bridge. The master communication bridge resumes the network adapter and the API.

Abstract: A method and a system for magnetic resonance imaging are provided. The method includes acquiring a magnetic resonance (MR) data set of an object by sampling only a portion of a k-space of the object. This sampled portion may be substantially triangle-shaped or be composed of multiple planes that extend through a point of origin of the k-space and are tangential to a common spherical cap in the k-space. An inverse Fourier transformation is then applied to the MR data set to transform the MR data set from the k-space to image space. A final MR image with a fan- or cone-beam geometry is then computed based on the transformed MR data set in image space.

Abstract: The present invention relates to a processing of digitally measured signals. When sampling a measurement signal with a predetermined sampling rate, aliasing effects may occur, if a Nyquist condition is violated. For this purpose, the present invention suggests to analyze a frequency spectrum of a signal and to compare the frequency components of the spectrum with the setting of a measurement apparatus, in particular a sampling rate of the measurement apparatus. If a measurement signal comprises frequency components which may violate the Nyquist condition, an alert may be generated to adapt the set of the measurement arrangement.
