Abstract: A control system for a motor vehicle having a first control unit for controlling a first function of the motor vehicle and a second control unit for controlling a second function of the motor vehicle. In order to ensure, with the least possible additional complexity, that functions of a motor vehicle that are controlled by means of control units are properly executed even in the event of a faulty control unit, the control system has a third control unit for controlling the first function and the second function of the motor vehicle and, depending on the receipt of a fault signal of the first and/or second control unit by the third control unit, the third control unit can be configured such that the motor vehicle first and/or second function corresponding to the faulty control unit can be controlled by means of the third control unit alone.

Abstract: In a method and apparatus for magnetic resonance imaging, a particularly quiet magnetic resonance sequence, uses echo-planar imaging with at least one gradient switching in a readout direction, wherein the at least one gradient switching in the readout direction has a slew rate that is less than a maximum slew rate defined by system specification parameters of the magnetic resonance apparatus.

Abstract: In a method and a magnetic resonance system for acquiring MR data in a predetermined volume segment of an examination subject, an RF excitation pulse is radiated and MR data are acquired along trajectories extending radially through the center of k-space. The MR data of one k-space spoke, which corresponds to one half of a trajectory, are acquired while gradients are switched. Starting from the same RF excitation pulse, only MR data of one k-space spoke are acquired by starting in the k-space center, acquiring the MR data continuously up to the k-space periphery. The echo time is greater than 1 ms.

Abstract: For each k-space line, a time period is defined that starts with the application of the RF pulse directly prior to the acquisition of the respective k-space line, and ends at the time point of the echo during the acquisition of the MR data of the respective k-space line. This time period is set shorter for those k-space lines that lie in a central region of k-space than for k-space lines that lie outside of the central region.
