1. A local coil arrangement configured for a magnetic resonance tomography system, the local coil arrangement comprising:
- an antenna element configured for reception of signals from an object under examination;
an A/D converter configured for conversion of analog signals received with the antenna element into digitized signals before transmission to a receiver outside of the local coil arrangement, the A/D converter being positioned locally within the local coil arrangement;
a memory configured for the storage of the digitized signals;
a device configured for one or more transmissions of the digitized signals stored in the memory, the device comprising a USB connection configured for cable-based transmission of the digitized signals that have been stored in the memory.

25. A method of storing signals in a local coil arrangement of a magnetic resonance tomography system, the method comprising:
-
receiving, with an antenna element, signals transmitted from an object under examination; converting, with at least one A/D converter of the local coil arrangement, analog signals received with the antenna element into digitized signals before transmission to a receiver outside of the local coil arrangement, the A/D converter being positioned locally within the local coil arrangement; storing the digitized signals in a memory located within the local coil arrangement; and transmitting, with a device comprising a USB connection configured for one or more cable-based transmission of the digitized signals, the digitized signals stored in the memory.
