摘要： The present invention relates to a method (100) for providing audio to a subject (200) undergoing a diagnostic imaging or medical procedure. The method comprises receiving (101) at least one audio stream and receiving (102) a definition of at least one source point in a three-dimensional space. The method comprises transforming (103) the at least one audio stream into at least two audio signals for corresponding sound outlets, in which these sound outlets are in a predetermined physical spatial configuration with respect to the subject during the procedure. The method also comprises outputting (105) the at least two audio signals to the corresponding sound outlets to produce sound audible by the subject. The step of transforming (103) comprises spatially encoding the audio stream into the at least two audio signals such that the produced sound corresponding to the audio stream appears, to the subject, to originate from the defined source point.

摘要： The present invention is directed to inductively feeding a RF coil (9) for magnetic resonance imaging (MRI), and in particular to a system comprising a RF coil (9) for magnetic resonance imaging and at least one feeding coil (14) for inductively feeding the RF coil (9) with an RF signal, and further to a method for inductively feeding a RF coil (9) for magnetic resonance imaging with at least one RF signal. According to the invention, in this system, the at least one feeding coil (14) is configured and arranged for feeding the RF signal into a conductive coil element (10) of the RF coil (9) at a first position and at a second position, the first position being different from the second position, wherein the direction of the magnetic field of the RF signal at the first position is different from the magnetic field of the RF signal at the second position. In this way, the invention provides for an inductive RF feeding of a resonator which can be achieved in a compensated way, i.e. the local RF field of the feeding loop can be compensated at distant locations. Moreover, the directions of the magnetic fields can be adapted to the respective direction of the magnetic field surrounding the coil element (10) at the respective feeding location. In this way, the invention enables to improve the power efficiency of an RF coil.

摘要： The present invention provides a rheology module (200) for use in a magnetic resonance (MR) rheology imaging system (110), whereby the rheology module (200) is adapted to introduce mechanical oscillations into a subject of interest(120), comprising a housing(202), a mechanical oscillator unit(204), which extends at least partially outside the housing (202) and is movable relative to the housing(202), and a transducer (206) for moving the oscillator unit(204),whereby the rheology module (200) comprises at least one radio frequency (RF) antenna unit(210, 212), which comprises at least one RF coil(214, 216).With the RF antenna device integrated into the rheology module, an antenna placement close to a region of interest (ROI) can be achieved to improve the MR imaging capabilities of a MR rheology imaging system. Thus, imaging of the ROI can be performed more efficiently. Furthermore, connection and cabling can be facilitated, since only one module has to be connected to generate the oscillation and to operate the RF antenna device.
