Abstract: In a method and magnetic resonance system for registering magnetic resonance signals of a subject and reconstructing an image on the basis of the registered magnetic resonance signals, an operator provides a control device of the magnetic resonance system with a reconstruction region in a phase-coding direction within which the image should be reconstructed on the basis of the magnetic resonance signals to be registered. The control device effects the registration of the magnetic resonance signals in the phase-coding direction beyond the reconstruction region as well in two independently selectable supplemental regions that are disposed at both sides of the reconstruction region in the phase-coding direction and which immediately adjoin said reconstruction region.

Abstract: In a method for determining the position of at least one local antenna in an examination space of a magnetic resonance (MR) system, magnetic resonance signals emitted by a body arranged in the examination space are received by the at least one local antenna location-encoded in at least one coordinate direction, intensity values that are spatially resolved in the coordinate direction are generated from the received magnetic resonance signals, and the position of the local antenna in the coordinate direction is determined from a curve of the intensity values along the coordinate direction, the intensity values having been subjected as needed to post-processing. The determination of the position of the local antenna ensues by adapting a function to the curve of the intensity values, the function being manipulable to approximate the shape of a sensitivity profile of the local antenna, and the position of a maximum of the adapted function is utilized as the position of the local antenna.

Abstract: In a method and apparatus for generating a combined parameter map from a number of individual, initial parameter maps that contain values of various parameters dependent on the position (x, y), for each of the initial parameter maps and for each position, the signal value of the parameter at the appertaining position is converted into a first color value according to a first transfer function specifically defined for the respective parameter. Subsequently, the first color values are respectively converted into color code intensity values on the basis of a second transfer function. The color code intensity values of the individual parameters are then operated to form a combined intensity value. Finally, the combined intensity value is converted with a third transfer function into a color value at the appertaining position in the parameter map.

Abstract: It is the object of the invention to supply an integrated circuit that contains a processor and at least one module and provides registers required for the modules as well as access to these registers. By concentrating the required registers according to the invention in a central register bank, which like the processor and the modules is connected to a fast AMBA-AHB bus, several advantages are achieved: for one, faster access is possible to each register. For another, the placement of the registers and the routing for the registers is simplified. This in particular allows chip area to be saved, which leads to cost savings in manufacture and enables higher component density. Furthermore, a slow AMBA-APB bus has now become optional.
