Abstract: In a method and control device for determining the position in at least one spatial direction of a local coil on a patient table in a scanner of a magnetic resonance tomography apparatus, a radio-frequency signal is emitted in the presence of a magnetic field gradient applied in the appertaining spatial direction and a signal profile is measured by the local coil along the magnetic field gradient. The signal profile is acquired for each of a number of positions of the patient table relative to the scanner along the magnetic field gradient. Based on the measured signal profile the position of the local coil is determined.

Abstract: In a method for determination and representation of adjustment steps for operation of an apparatus requiring adjustment, such as a diagnostic imaging apparatus, the implementation of manual adjustments by a user is supported. The method determines which adjustment steps are necessary for adjustment of the apparatus for a particular operation thereof and displays then in a list on a display medium. The adjustment steps are ordered corresponding to a sequence that is necessary for adjustment of the apparatus.

Abstract: In a method for determining an acceleration factor of a parallel image acquisition for a data acquisition direction of a measurement volume by means of a magnetic resonance device having multiple coil units, each coil unit emits at least one output signal for parallel image acquisition and wherein an acceleration contribution is assigned for at least one direction (X,Y,Z) for a sensitive volume. Relevant coil units, which by virtue of the arrangement of their sensitive volume in relation to the measurement volume contribute to the acceleration, are specified. The data acquisition direction in the measurement volume is specified and the acceleration factor in this direction is determined by means of acceleration contributions depending on the position of the relevant coil units with respect to one another and the position of the relevant coil units in relation to the measurement volume and to the data acquisition direction.

Abstract: In a method for generation of magnetic resonance exposures and a control device for a magnetic resonance tomography apparatus, a number of coils are available in the apparatus, the coils being are positioned at various locations relative to the examination subject. Initially a radio-frequency signal is emitted and a spatially-resolved signal intensity distribution is measured with at least one or some of the available coils. An automatic determination of a three-dimensional exposure profile of the appertaining coils is made based on the received signals. A selection of one or more of the appertaining coils for a subsequent magnetic resonance measurement is made on the basis of the determined exposure profiles of the coils as well as the measurement region to be acquired in the magnetic resonance measurement.

Abstract: In a method for implementation of a magnetic resonance examination of a patient with an imaging medical magnetic resonance apparatus with a movable patient bed, for of an examination volume of the patient that is larger than an acquisition volume of the magnetic resonance apparatus, anatomical patient information and second technical information for setting the magnetic resonance apparatus are acquired dependent on the position of the patient bed from magnetic resonance signals acquired in a low-resolution calibration measurement (scan). A first group of measurement protocol parameters is generated from the patient information and a second group of measurement protocol parameters is generated from the technical information, to generate a measurement protocol for a subsequent high-resolution magnetic resonance examination.
