摘要： A method is described for the wireless signal transmission of a measurement signal and/or a control signal between two functional components of a MR system. The measurement signal and/or the control signal is encoded into a RF transmit signal with a predefined orbital angular momentum and this RF transmit signal is transmitted between transmit antenna arrangements of the functional components. In addition, the embodiments relate to a local coil and an orbital angular momentum transmit unit with which the method may be carried out, and also a MR system that has a local coil and an orbital angular momentum transmit unit of this type.

摘要： In a method to determine phase and/or amplitude between interfering, adjacent x-ray beams in a detector pixel in a Talbot interferometer for projective and tomographical x-ray phase contrast imaging and/or x-ray dark field imaging, after an irradiation of the examination subject with at least two coherent or quasi-coherent x-rays, an interference of the at least two coherent or quasi-coherent x-rays with the aid of an irradiated phase grating is generated, and the variation of multiple intensity measurements in temporal succession after an analysis grating is determined in relation to known displacements of one of the gratings or of an x-ray source fashioned like a grating, positioned upstream in the beam path, relative to one of the gratings. The integrating intensity measurements ensue during a relative movement—thus not during the standstill—of one of the upstream gratings or of the x-ray source fashioned like a grating or of the examination subject, with known speed behavior over a final time interval of a final distance.
