摘要： The embodiments relate to a method for the optimization of alignment measurements in which a MR facility is configured to a measurement object. First alignment measurements are carried out while the measurement object is being moved through the MR facility, wherein at least one MR system parameter of the MR facility is configured to the measurement object of the first alignment measurements. A second alignment measurement is also carried out in which the measurement object is stationary in a fixed position in the MR facility, wherein the second alignment measurement includes an iterative alignment method in which the at least one MR system parameter for the recording of MR signals of the measurement object is iteratively configured to the measurement object in the fixed position in the MR facility, wherein for the iterative alignment method the aligned MR system parameter is chosen from the aligned MR system parameters.

摘要： In a method for determination of a position of a local coil on a bed in at least one spatial direction within a magnetic resonance scanner, a signal intensity value is initially, extracted from magnetic resonance measurements implemented with the appertaining local coil for acquisition of magnetic resonance images of an examination subject and/or for measurement of further system parameters at each of various positions of the recumbent bed relative to the tomograph. The functional dependency of the extracted signal intensity values on the position of the bed relative to the scanner is then determined. The position of the local coil on the bed is determined on the basis of the determined functional dependency. A corresponding control device for a magnetic resonance system and a computer program product implement the method.

摘要： 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.

摘要： A method for operating a magnetic resonance tomograph having at least one receiving antenna, at least one converter device for analog/digital conversion and a programmable computing device is provided. The method includes generating, with the converter device, digital measured values by digitizing the analog reception signal from the receiving antenna and/or at least one analog signal derived from the reception signal. A time-coding device adds an item of time information that describes the recording time of the measured values to each of the digital measured values or to groups of measured values including a plurality of the digital measured values in order to generate a time-coded data stream. The programmable computing device processes the time-coded data stream further.
