摘要： In the generation of MR angiography images of a predetermined three-dimensional volume segment of a living examination subject using means a magnetic resonance system, MR data in the volume segment are acquired by radial acquisition of k-space. The MR data are analyzed in order to subdivide the MR data into groups, with each group including only the MR data that correspond to a specific heart beat phase of the heat of the examination subject. MR angiography images are generated based only on the MR data of one of these groups.

摘要： An auscultation apparatus including an optical microphone is proposed. Optical microphones can reliably acquire sounds of the most disparate frequencies even in an environment permeated by electromagnetic fields, without influencing said fields. Such an optical microphone of an auscultation apparatus can be disposed inside a medical examination and diagnostic device during operation. Given a suitable arrangement, both the heart sounds and the respiratory sounds of a patient can be recorded and monitored already with just one optical microphone.

摘要： A method tracks contrast agent in a magnetic resonance tomography examination with examination table moving continuously in the Z-direction. In the method, a first magnetic resonance signal in a first magnetic resonance measurement without contrast agent. The first MR signal is acquired along a middle k-space line that runs essentially in the Z-direction. Values of k-space along the middle k-space line of the first MR signal are transformed by means of a Fourier transformation in the Z-direction in order to obtain a first profile of the signal intensity in the Z-direction. After a contrast agent injection, a second MR signal is acquired in a second magnetic resonance measurement. The second MR signal is acquired along the middle k-space line. Values of k-space along the middle k-space line of the second MR signal are transformed by a Fourier transformation only in the Z-direction in order to obtain a second profile of the signal intensity with contrast agent in the Z-direction. A difference profile is determined from the first profile and the second profile. A signal jump in the difference profile is used to determine a propagation edge of the contrast agent.

摘要： For radial data acquisition in three-dimensional k-space in an MR measurement for a magnetic resonance system, data in k-space are acquired along straight-line spokes. Each of the spokes is thereby defined by a point on a sphere and the center point of this sphere, wherein the center point corresponding to the center of k-space. The points are arranged on the sphere such that a distribution of the points obeys the spiral phyllotaxis, in particular the Fibonacci phyllotaxis.

摘要： In a method and apparatus for time-resolved acquisition of magnetic resonance (MR) data, an examination subject is continuously moved through the examination region of an MR scanner, and MR signals are acquired. Prior to the acquisition of MR signals, a phase coding that corresponds to a position for data entry in k-space is carried out. An interruption of the movement of the subject takes place at a predetermined table position, and the acquisition of MR signals is continued over the course of a predetermined time period, while the subject is at rest in the predetermined position. At least while the subject is at rest, the phase coding causes acquisition of a predetermined number of MR signals for filling a first region of k-space to alternate with MR data and a predetermined number of MR signals for filling a second region of k-space.
