摘要： In a method and a pulse sequence determination device to determine a pulse sequence for a magnetic resonance system, control protocol parameter values are initially acquired. A determination of k-space trajectory node points within k-space then takes place in a processor on the basis of the control protocol parameter values. The determination of the pulse sequence then takes place on the basis of the k-space trajectory node points. A method for operating a magnetic resonance system uses such a pulse sequence, and a magnetic resonance system embodies such a pulse sequence determination device.

摘要： In a method and apparatus for acquiring magnetic resonance data, a resting state functional magnetic resonance imaging sequence is executed in alternation with a morphological data acquisition sequence. The alternating sequences are executed with no time interruptions therebetween, with at least one repetition of the alternating sequences. The resting state functional magnetic resonance imaging sequence can be a BOLD-EPI sequence, and the morphological imaging sequence can be an MPRAGE sequence.

摘要： In a method to measure characteristic structure sizes of the human brain, which structure sizes can be used as biomarkers for a diagnosis of Alzheimer's, using a magnetic resonance device, manual and/or automatic localization of the hippocampus takes place in a preliminary magnetic resonance acquisition, followed by selection of at least one measurement axis that proceeds through the hippocampus. For each selected measurement axis, magnetic resonance data are acquired for a longitudinal, in particular rod-shaped, acquisition region proceeding along the measurement axis. Determination of the spatially resolved structure sizes is implemented from the magnetic resonance data.

摘要： A method is for recording and evaluating image data with the aid of a tomography machine. At least two recordings with different spectral distribution are made of an examination area of an object. Further, measured data obtained from the two recordings are evaluated such that additional information relating to the examination area and/or a specific representation of the image of the examination area are/is obtained from the different spectral distributions. The tomography machine includes at least two separate recording systems. Further, it is operated such that the two recording systems operate with a different spectral distribution. As such, the additional information and the specific representation of an image can be obtained in conjunction with a reduced scanning time.

摘要： A method is disclosed for producing a computed tomography display of tissue structures by applying a contrast medium. A contrast medium is applied to a patient for better visualization of the tissue structure to be examined. An X-ray scan is performed during the presence of the one contrast medium, and computed tomography 2- or 3-dimensional pictures are subsequently reconstructed from the X-ray scan data obtained. In the method, absorption data are measured for at least two different energy spectra, a computed tomography intermediate image is reconstructed per energy spectrum, and the distribution of the one contrast medium in the tissue is determined from the different energy-specific absorption behavior between tissue and contrast medium.

摘要： A method is proposed for producing an anti-scatter grid or collimator for a radiation type, which is formed from at least one base body of prescribable geometry having transmission channels or slits for primary radiation of the radiation type which extend between two opposite surfaces of the base body. The base body is formed from a structural material that strongly absorbs the radiation type, either using the injection molding technique or by way of the technique of stereolithography. The method can be used to produce an anti-scatter grid or collimator with high accuracy and with the aid of only a few steps.

摘要： A method includes dividing a scanning volume into a multiplicity of partial volumes. For each partial volume, a reference beam is sought, which intersects the partial volume and which is at the greatest distance from the system axis. Further, the absorption coefficients of each partial volume are calculated exclusively with absorption values that originate from beams whose distance is greater than or equal to the distance between the reference beam and the system axis.
