摘要： An apparatus and a method for generating an image from N reception signal data sets of signals received by a plurality of coils of a magnetic resonance tomography appliance from a region of a body to be examined using an image processing computer are provided. The apparatus includes a degree-of-compression determining device. A ratio N/M of the number N of N reception signal data sets generated from the signals received by the plurality of coils to a smaller number M of mode data sets is defined taking account of a plurality of parameters. The plurality of parameters at least also represent system resources of the image processing computer. Using a compression computer, the N reception signal data sets are compressed into M mode data sets. After this, the M mode data sets are used by the image processing computer for generating the image of the region of the body.

摘要： A local coil for magnetic resonance applications includes a rigid housing that radially surrounds a substantially cylindrical examination volume. Arranged in the rigid housing is a transmitting coil, by which an excitation signal may be applied to the examination volume. An object to be examined arranged in the examination volume may be excited by the excitation signal for emitting a magnetic resonance signal. The local coil includes a size-variable structure, in which an antenna assembly for receiving the magnetic resonance signal emitted by the object to be examined is arranged. The size-variable structure is arranged in the examination volume and is connected to the rigid housing. The size-variable structure is soft and flexible.
